Description

A kind of flexible sole of damping

Technical field

This utility model is related to footwear technical field, the flexible sole of more particularly to a kind of damping.

Background technology

Shoes are indispensable necessarys in daily life, in response to different effects and external form, have various each on the market The a feast for the eyes species of sample, but no matter how the outward appearance of shoes changes, the protection enough with providing foot comfortable and easy to wear is only Most important.

Plantar fascia is the thick knot hoof tissue of thick layer, and its motion feature during contacting to earth is：Heel lateral is first Land, now plantar fascia starts to stretch, and then whole heel lands, then is transitioned into mesopodium, then to forefoot, entirely slap Ground；And then after heeloff, then to mesopodium, it is exactly finally to pedal less touch with the ground, plantar fascia recoils to naturalness, plantar fascia Stretching and resilience contribute to strengthening the bradyseism ability of foot, but the design of existing footwear sole construction but could not combine vola well Fascia, the damping performance of sole and snugness of fit need to improve further and improve.

Utility model content

For overcoming the technological deficiency of prior art presence, this utility model provides a kind of flexible sole of damping, can be with foot Step action bends moderately and at the right moment naturally, and can give sole more preferably bradyseism effect, meet plantar fascia anatomical features and Foot movement principle.

This utility model adopt technical solution be：

A kind of flexible sole of damping, including with the corresponding sole forepart of forefoot and mesopodium position, described sole forepart Interior lateral surface on be equipped with damping wall trench, each damping wall trench is in the groove structure that middle width two ends are narrow and middle depth two ends are shallow； The bottom surface time interval of described sole forepart is provided with transverse concave groove, and the two side in front and back of each transverse concave groove is all in along sole forepart It is wavy that left and right directions wave extends；Sole forepart between adjacent two transverse concave grooves respectively left and right be arranged at intervals with four indulge To groove, be set between adjacent two longitudinal flutings respectively with plantar fascia position longitudinal boss correspondingly, and near footwear It is provided with damping space in the longitudinal fluting in bottom front inner face.

Preferably, the bottom surface of described sole forepart is provided with two transverse concave grooves, and one of transverse concave groove is closed with sole of the foot toe Section position corresponds to, and another one transverse concave groove is corresponding with metatarsal middle and upper part position.

Preferably, sequence before and after the crest of the front-rear side walls of described transverse concave groove corresponding with metatarsophalangeal joints, with the sole of the foot Corresponding before and after the crest of front-rear side walls of the corresponding described transverse concave groove in bone middle and upper part position.

Preferably, it is respectively equipped with, in described longitudinal fluting, the elastic strip being made up of high density elastomeric material, this elastic strip Bottom surface level height is more than the level height of longitudinal boss bottom surface of both sides.

Preferably, the depth of described transverse concave groove is more than the depth of longitudinal fluting.

Preferably, described longitudinal boss is respectively equipped with anti-skidding burr.

Preferably, lateral surface in the sole forepart at each transverse concave groove two ends is respectively equipped with protuberance.

The beneficial effects of the utility model：Due to being provided with the transverse concave groove and between left and right of time interval in sole forepart bottom surface Every longitudinal fluting, the sole forepart between adjacent longitudinal fluting is set to longitudinally convex correspondingly with plantar fascia position respectively Platform, can make this utility model sole forepart have good bending performance using transverse concave groove, can be in good time with footwork Appropriateness bending and reset, naturally smooth；Give foot one the stable effect supporting using longitudinal boss, simultaneously longitudinal boss Telescoping collapse can absorb ground shock power and store and rebound motion energy, strengthen cushioning ability and the energy bounce-back of sole, Meet anatomical features and the foot movement principle of plantar fascia；Using longitudinal fluting so that longitudinal boss is in the loading process that contacts to earth In there is preferably elasticity and contractility, increase the bradyseism ability of longitudinal boss；And, the damping on lateral surface in sole forepart Wall trench and contribute to greatly promoting sole forepart near the damping space in the longitudinal fluting of sole forepart medial surface and contacted to earth Bradyseism ability in journey, reduces the sense of discomfort to foot for the ground shock power, the comfort level of lifting sole dress.

Specific embodiment

The utility model is described in further detail below in conjunction with the accompanying drawings：

As Figure 1-3, the present embodiment provides a kind of flexible sole of damping, including corresponding with forefoot and mesopodium position Sole forepart.

In the present embodiment, the interior lateral surface of described sole forepart is equipped with damping wall trench 10, each damping wall trench 10 is in The groove structure that middle width two ends are narrow and middle depth two ends are shallow.

In the present embodiment, the bottom surface time interval of described sole forepart is provided with transverse concave groove 20, and each transverse concave groove 20 Before and after two side wavy all in extend along sole forepart left and right directions wave.On the bottom surface of preferably described sole forepart Be provided with two transverse concave grooves 20, one of transverse concave groove 20 is corresponding with metatarsophalangeal joints position, another one transverse concave groove 20 with Metatarsal middle and upper part position corresponds to.It is staggered before and after the crest of the front-rear side walls of described transverse concave groove 20 corresponding with metatarsophalangeal joints Position, corresponding before and after the crest of front-rear side walls of described transverse concave groove 20 corresponding with metatarsal middle and upper part position.

In the present embodiment, left and right is arranged at intervals with four longitudinal directions to the sole forepart between adjacent two transverse concave grooves 20 respectively Groove 30, be set between adjacent two longitudinal flutings 30 respectively with plantar fascia position longitudinal boss 40 correspondingly, described vertical Anti-skidding burr is respectively equipped with boss 40, and is provided with damping space near in the longitudinal fluting 30 of sole forepart medial surface, Described damping space from this longitudinal fluting 30 near the medial wall of sole forepart medial surface relative to sole forepart bottom surface to inner side and The depression that is inclined upwardly is formed.

In the present embodiment, it is respectively equipped with, in described longitudinal fluting 30, the elastic strip 31 being made up of high density elastomeric material, The bottom surface level height of this elastic strip 31 is more than the level height of longitudinal boss 40 bottom surface of both sides.The depth of described transverse concave groove 20 Degree is more than the depth of longitudinal fluting 30.Further, lateral surface in the sole forepart at each transverse concave groove 20 two ends is respectively equipped with Protuberance, this protuberance is conducive to strengthening transverse concave groove 20 effective return after going power.
