Description
- The present invention relates to a climbing shoe.
- As is known, climbing shoes generally comprise: a leather shoe-upper which is substantially sock-shaped so as to accommodate and completely cover the foot, including the sole of the foot; a front tensioning band made of highly elastic rubber, which is substantially U-bent and is fixed by gluing onto the tip of the shoe-upper so as to surround the tarsus-phalangeal region of the foot; a rear tensioning band made of highly elastic rubber, which is substantially U-bent and is fixed by gluing to the rear part of the shoe-upper so as to cover the region above the calcaneus of the foot, and then extends along the two lateral sides of the shoe-upper up to meet and join to the front tensioning band; and a sole made of soft and flexible elastomeric material with a high friction coefficient and substantially non-extendible, which is fixed by gluing to the bottom of the shoe-upper, above the front and rear tensioning bands, so as to cover the whole of the sole of the user's foot.
- In some models of climbing shoe, the sole is moreover provided at the back with a large oblong tongue that rises along the heel up to the height of the rear tensioning band, while remaining substantially astride the midplane of the shoe, and in addition overlaps two protective inserts made of low-elasticity rubber or other similar elastomeric material, which are substantially seashell-shaped and are fixed by gluing to the two lateral sides of the shoe-upper so as to cover and protect both sides of the calcaneus of the user's foot.
- The document
EP2949232 discloses a climbing shoe according to the preamble of claim 1. - Unfortunately, experimental tests have found that the rear part of the climbing shoe is frequently subject to particularly high tangential stresses that, in some cases, discharge directly onto the lateral side of the rear tongue of the sole, initially causing fraying of the tongue and then its complete detachment, with all the problems that this entails on the structural integrity of the sole.
- Aim of the present invention is therefore to provide a climbing shoe that overcomes the drawbacks described above.
- In compliance with this aims, according to the present invention there is provided a climbing shoe as defined in Claim 1, while secondary embodiments are defined in the dependent claims.
- The present invention will now be described with reference to the accompanying drawings, which illustrate a non-limiting embodiment thereof, in which:
-
Figure 1 is a perspective and schematic view of a climbing shoe realized according to the teachings of the present invention; whereas -
Figures 2, 3 ,4 ,5 and 6 are respective perspective views of the shoe inFigure 1 with parts removed for the sake of clarity. - With reference to
Figures 1 to 6 , reference number 1 denotes as a whole a climbing shoe that may be particularly advantageously used for climbing on rock walls classified as grade IV or higher, where climbers usually have to use the heel of their foot for progressing in the climbing. - The climbing shoe 1 basically comprises: a shoe-upper 2, preferably made of leather, which is substantially sock-shaped so as to accommodate and completely cover the foot of the user, including the sole of the foot; and a front sole 3 made of a soft and flexible elastomeric material with a high friction coefficient and substantially non-extendible, which is firmly fixed to the bottom or insole 4 of the shoe-upper 2, preferably by gluing.
- More in detail, the bottom or
insole 4 of the shoe-upper 2 is divided longitudinally into a front or tarsus-phalangeal portion 4a that is immediately underneath the tarsus-phalangeal region of the sole of the user's foot; a central or plantar-arch portion 4b that is immediately underneath the plantar arch region; and a rear or talus-calcaneal portion 4c that is immediately underneath the talus-calcaneal region of the sole of the user's foot. - The
front sole 3 is preferably made of a soft and flexible elastomeric material with a hardness (UNI 4916) preferably lower than 80 ShoreA and optionally ranging between 69 and 75 ShoreA, and is shaped so as to cover the tarsus-phalangeal portion 4a of thebottom 4 of shoe-upper 2, preferably roughly up to the border with the plantar-arch portion 4b of thebottom 4 of shoe-upper 2. - In other words, the front sole 3 only covers a portion of the bottom or insole 4 of shoe-upper 2.
- Preferably, moreover, the
front sole 3 is made of a soft and flexible elastomeric material with a density (UNI 7092) preferably comprised between 1.12 and 1.50 g/cm3 (grammes per cubic centimetre). - More in detail, in the example shown, the
front sole 3 is preferably made of a soft and flexible elastomeric material such as, for example, the XS Edge compound or theGRIP 2 compound manufactured by VIBRAM. - In the example shown, furthermore, the
front sole 3 is preferably shaped so as to more or less completely cover the tarsus-phalangeal portion 4a of thebottom 4 of shoe-upper 2a, and optionally also a small area/region of the plantar-arch portion 4b. - The climbing shoe 1 moreover comprises a
rear sole 5 which is likewise made of a soft and flexible elastomeric material with a high friction coefficient and substantially non-extendible, and is firmly fixed to the bottom or insole 4 of the shoe-upper 2, preferably by gluing. - More in detail, similarly to front sole 3,
rear sole 5 is preferably made of a soft and flexible elastomeric material with a hardness (UNI 4916) preferably lower than 80 ShoreA and optionally ranging between 69 and 75 ShoreA, and is shaped so as to at least partially cover the talus-calcaneal portion 4c of thebottom 4 of shoe-upper 2. - The
rear sole 5 is thus separate, discrete and spaced apart from the front sole 3. - In the example shown, in particular, the
rear sole 5 is equally preferably made of a soft and flexible elastomeric material such as, for example, the XS Edge compound or theGRIP 2 compound manufactured by VIBRAM. - With reference to
Figures 1 ,4 ,5 and 6 , furthermore the climbing shoe 1 additionally comprises one or more tensioning bands made of elastic material, i.e. of a material with an elastic modulus (also known as Young's modulus) significantly lower than that ofsoles - Preferably, the elastic-material tensioning band or bands are moreover pre-tensioned in order to embrace and tighten the shoe-upper 2 strongly onto the foot of the user, and optionally also so as to bend/curve downwards the foot of the user.
- More in detail, the climbing shoe 1 is preferably provided with at least one
front tensioning band 6 and at least onerear tensioning band 7, both preferably pre-tensioned, which are preferably made of highly elastic rubber or other elastomeric material with an elastic modulus 2-3 times lower than that of sole 3 and/or of sole 5, and are finally firmly fixed to the shoe-upper 2 preferably by gluing. - The
front tensioning band 6 surrounds thetip 8 of the shoe-upper 2. Therear tensioning band 7 instead surrounds the rear part of the shoe-upper 2, remaining substantially above theheel portion 9 of the shoe-upper 2, i.e. above the portion of shoe-upper 2 that covers the rear end of the calcaneus of the user's foot. - In the example shown, in particular, the
tensioning bands - Preferably, furthermore, the
tensioning bands - More in detail, with specific reference to
Figures 1 ,5 and 6 , thefront tensioning band 6 is substantially U-bent and is firmly fixed to thetip 8 of the shoe-upper 2 so as to surround/embrace the tarsus-phalangeal portion of the foot of the user, i.e. the front part of the foot, preferably also extending/prolonging on the tarsus-phalangeal portion 4a of thebottom 4, underneath the front sole 3. - Preferably, the two
ends 6a offront tensioning band 6 furthermore extend on thebottom 4 of shoe-upper 2 one towards the other, so as to meet/join firmly together preferably at the tarsus-phalangeal portion 4a and/or the plantar-arch portion 4b of thebottom 4. - More in detail, the two
ends 6a offront tensioning band 6 preferably overlap and are glued one over the other, directly at the portion ofbottom 4 of shoe-upper 2 located substantially astride the tarsus-phalangeal region and the plantar arch region of the sole of the user's foot. - In other words, the two ends 6a of
front tensioning band 6 preferably overlap and are glued one over the other roughly at the border between theportions bottom 4 of shoe-upper 2. - Preferably, furthermore, the
central segment 6b offront tensioning band 6 is substantially hood-shaped, so as to cover and protect both the sides and the upper part of thetip 8 of the shoe-upper 2, i.e. the part of shoe-upper 2 on the opposite side of the sole 3. - In the example shown, moreover, the
central segment 6b offront tensioning band 6 is preferably shaped so as to also extend on the part of shoe-upper 2 covering the instep of the user's foot. - With reference to
Figures 1 ,4 ,5 and 6 , therear tensioning band 7, in turn, is substantially U-bent and is fixed to the rear part of shoe-upper 2, so as to cover the area of the shoe-upper 2 immediately above theheel portion 9, and then extends along the two inner and outerlateral sides 10 of shoe-upper 2 towards the front sole 3, preferably up to reach and join thefront tensioning band 6, preferably by gluing. - More in detail, the
rear tensioning band 7 is preferably structured so as to reach and join thefront tensioning band 6 along thelateral sides 10 of the shoe-upper 2, close to thebottom 4 of shoe-upper 2 and near the border between theportions bottom 4, i.e. near the border between the tarsus-phalangeal region and the plantar arch region. - Preferably, the two
ends 7a ofrear tensioning band 7 furthermore extend the other on thebottom 4 of shoe-upper 2 one towards, affecting the plantar-arch portion 4b of thebottom 4 and optionally also the tarsus-phalangeal portion 4a and/or the talus-calcaneal portion 4c of thebottom 4. - Additionally, the two
ends 7a ofrear tensioning band 7 extend on thebottom 4 of shoe-upper 2 so as to meet and firmly joined to one another and/or to the twoends 6a offront tensioning band 6, preferably by gluing, roughly at the plantar-arch portion 4b of thebottom 4. - More in detail, with reference to
Figures 4 and5 , in the example shown the twoends 7a ofrear tensioning band 7 are preferably shaped so as to cover substantially the whole of the plantar-arch portion 4b of thebottom 4 of shoe-upper 2, in addition to a small sector of tarsus-phalangeal portion 4a and a small sector of talus-calcaneal portion 4c. - Preferably, the two
ends 6a offront tensioning band 6, in turn, extend along thebottom 4 of shoe-upper 2 so as to go beyond the border between the tarsus-phalangeal portion 4a and the plantar-arch portion 4b, in order to overlap the twoends 7a ofrear tensioning band 7 at the plantar-arch portion 4b of thebottom 4. - With reference to
Figures 1 to 6 , on the other hand, therear sole 5 is shaped and arranged so as to cover, preferably substantially entirely, the talus-calcaneal portion 4c of thebottom 4 of shoe-upper 2, and theheel portion 9 of shoe-upper 2 (i.e. the portion of shoe-upper 2 that covers the end of the calcaneus of the user's foot), preferably up to the height ofrear tensioning band 7. - In addition, the climbing shoe 1 furthermore comprises a pair of lateral
protective inserts 11 made of low-elasticity rubber or other similar elastomeric material, which are substantially shell-shaped and are firmly fixed to thelateral sides 10 of the shoe-upper 2, preferably by gluing, so as to be adjacent to therear sole 5 on opposite sides thereof, so as to cover and protect the two sides of the calcaneus of the user's foot. - Preferably, the lateral
protective inserts 11 moreover are made of an elastomeric material with a hardness greater than that of thematerial forming soles - More in detail, the
rear sole 5 is substantially L-bent so as to form a lowerflat portion 12 and an upperflat portion 13 substantially perpendicular to one another. - The lower
flat portion 12 covers the talus-calcaneal portion 4c of thebottom 4 of shoe-upper 2, preferably substantially up to the border with the plantar-arch portion 4b and preferably locally overlapping the twoends 7a ofrear tensioning band 7. - The upper
flat portion 13, in turn, covers theheel portion 9 of the shoe-upper 2 (i.e. the portion of shoe-upper 2 that covers the end of the calcaneus of the user's foot), preferably up to the height ofrear tensioning band 7 and preferably also extending underneath the central segment of therear tensioning band 7. - With reference to
Figures 1 to 6 , eachprotective insert 11, on the other hand, is roughly triangular in shape and is firmly fixed to the shoe-upper 2 so as to have a firstlateral border 11a adjacent to the upperflat portion 13 ofrear sole 5, and a secondlateral border 11b adjacent to the lowerflat portion 12 ofrear sole 5. Thelateral borders protective insert 11 are therefore consecutive and preferably also substantially perpendicular to one another. - In addition, each
protective insert 11 is moreover shaped so that itslateral border 11a covers/overlaps and is also firmly fixed to a corresponding and complementarylateral border 13a of the upperflat portion 13 ofrear sole 5, preferably substantially for the whole length of saidlateral border 13a. - More in detail, the
lateral border 11a ofprotective insert 11 is preferably fixed by gluing to the correspondinglateral border 13a of the upperflat portion 13 ofrear sole 5. - In other words, the vertical
lateral border 11a of eachprotective insert 11 overlaps and is firmly fixed to a corresponding and complementarylateral border 13a of the upperflat portion 13 ofrear sole 5. - Preferably, each
protective insert 11 is furthermore shaped so that itslateral border 11b continues/extends on the talus-calcaneal portion 4c of thebottom 4 of shoe-upper 2, towards the centreline of the flat portion, while remaining underneath the lowerflat portion 12 ofrear sole 5 and preferably also underneath theadjacent end 7a ofrear tensioning band 7. - In other words, the lower
flat portion 12 ofrear sole 5 overlaps thelateral border 11b of bothprotective inserts 11 and is firmly fixed to saidlateral borders 11b preferably by gluing. - Preferably, the two
ends 7a ofrear tensioning band 7 moreover at least partially cover/overlap thelateral borders 11b of the twoprotective inserts 11. - With particular reference to
Figure 4 , furthermore, the twolateral borders 13a of the upperflat portion 13 delimit, on the same upperflat portion 13, a substantially ribbon-likemedial strip 13b that preferably has a thickness greater than that of the twolateral borders 13a and/or greater than that of the twoprotective inserts 11, so as to form a vertical ridge or rib which extends substantially on the midplane of the shoe and protrudes/ juts out beyond the twoprotective inserts 11 that flank it. - In other words, the
medial strip 13b of upperflat portion 13 has a thickness greater than that of thelateral borders 13a, so as to form a vertical ridge or rib that covers and protects the calcaneus of the user's foot, and protrudes beyond the twoprotective inserts 11 flanking it. - Preferably, the
medial strip 13b of upperflat portion 13 additionally has an average width ℓ greater than 0.8 cm (centimetres), and preferably ranging between 1.2 and 2.5 cm (centimetres). - Lastly, the two
protective inserts 11 are preferably made of an elastomeric material having an elastic modulus both lower than that ofsoles tensioning bands - Lastly, with reference to
Figures 1 and6 , the climbing shoe 1 preferably also includes a substantially ribbon-likemedial tensioning band 14 which is firmly fixed to the bottom orinsole 4 of shoe-upper 2 substantially for its entire length preferably by gluing, and which extends roughly from the centre of the tarsus-phalangeal portion 4a ofbottom 4 roughly up to the centre of the talus-calcaneal portion 4c ofbottom 4, while remaining more or less astride the centreline ofbottom 4, so as to be able to prevent the elongation of shoe-upper 2. - In addition, the
medial tensioning band 14 extends underneath the front sole 3 and therear sole 5, and is firmly fixed to the front sole 3 and to therear sole 5 preferably by gluing. - More in detail, the
front sole 3 is firmly fixed to thebottom 4 of shoe-upper 2, above the front end ofmedial tensioning band 14, and is firmly fixed to themedial tensioning band 14 preferably by gluing. Likewise, therear sole 5 is firmly fixed to thebottom 4 of shoe-upper above the rear end ofmedial tensioning band 14, and is firmly fixed to the samemedial tensioning band 14 preferably by gluing. - Likewise the
tensioning bands medial tensioning band 14 is preferably made of highly elastic rubber or another elastomeric material with an elastic modulus significantly lower than that of front sole 3 and ofrear sole 5, and is preferably pre-tensioned. - Preferably, the
medial tensioning band 14 furthermore has a width always less than the width of thebottom 4 of shoe-upper 2, and extends along thebottom 4 of shoe-upper 2 from the tarsus-phalangeal portion 4a to the talus-calcaneal portion 4c of thebottom 4, preferably overlapping the twoends 6a offront tensioning band 6 and the twoends 7a ofrear tensioning band 7. - The functioning of climbing shoe 1 is easily inferable from the above description, and therefore does not require further explanation.
- The advantages resulting from the particular overlap between the rear sole 5 and the two lateral
protective inserts 11 are remarkable. - Firstly, the overlap between the
lateral borders 11a ofprotective inserts 11 and the two correspondinglateral borders 13a of the upperflat portion 13 of rear sole 5 prevents fraying of the rear sole 5 even under particularly high tangential stresses. - In addition, the protruding ridge or rib present along the
medial strip 13b of the upperflat portion 13 increases the grip on the rock, facilitating the climber during heel-hooking. - Lastly, the overlap of the lower
flat portion 12 to the lowerlateral borders 11b of the twoprotective inserts 11, at the talus-calcaneal portion 4c of thebottom 4, improves the containment characteristics of the shoe thus stabilising the user's heel. - It is finally clear that modifications and variations can be made to the climbing shoe 1 described and illustrated above without thereby departing from the scope of the present invention.
- For example, in a simplified embodiment, only one of the two lateral
protective inserts 11 is arranged on the shoe-upper 2 so that itslateral border 11a overlaps and is firmly fixed to the correspondinglateral border 13a of the upperflat portion 13 of rear sole 5. - More in detail, only the
protective insert 11 located on the outerlateral side 10 of shoe-upper 2 is preferably fixed to the shoe-upper 2 with thelateral border 11a overlapping the correspondinglateral border 13a of the upperflat portion 13 of sole 5. - Furthermore, according to an alternative embodiment, the rear sole 5 is made as a single piece with the front sole 3 so as to form a large monolithic sole made of soft and flexible elastomeric material with a high friction coefficient and substantially non-extendible, which is firmly fixed to the bottom or
insole 4 of shoe-upper 2 preferably by gluing, so as to cover the whole ofbottom 4, and in addition is provided at the back with a big flat portion or tongue that rises along theheel portion 9 of shoe-upper 2 preferably up to the height ofrear tensioning band 7, so as to cover and protect the part of the shoe-upper 2 that covers the calcaneus of the user's foot. - In this alternative embodiment, the
protective inserts 11 are firmly fixed to the lateral sides 10 of shoe-upper 2 in such a way that at least one of them has thelateral border 11a overlapping the corresponding and complementary lateral border of the rear flat portion or tongue of the monolithic sole. The lowerlateral borders 11b of the twoprotective inserts 11, in turn, extend on the talus-calcaneal portion 4c of thebottom 4 of shoe-upper 2 underneath the large monolithic sole. - Clearly in this embodiment the climbing shoe 1 lacks the
medial tensioning band 14.
