Description

SHOE
Field of the invention
The invention relates to a shoe as defined in the preamble of independent claim 1.
The shoe of the invention can advantageously be a sport shoe such as a running shoe, but the invention may also be used in the construction of other types of shoes for other purposes.
Several independent researches have shown that walking and running barefoot have benefit in strengthening muscles and the bone structure.
Walking and running barefoot is however not possible everywhere such as for example in cities because of litter, glass etc. Pieces of footwear for providing a barefoot feeling for the wearer and for providing for necessarily foot protection have therefore been developed.
Publication US 7,401,421 presents a sole construction for use in the manufacture of a shoe has an outsole made of a soft and pliable natural or synthetic elastomeric material having a substantially uniform thickness over its entire area. The outsole has a substantially planar external surface (when relaxed) for contacting the ground, with cuts formed therein to enhance grip. A puncture-resistant inner sheet of woven synthetic fibers is bonded to the internal surface of the outsole and an inner lining is bonded to the puncture-resistant inner sheet. A removable soft insole may be provided on the inner lining. The sole construction is lightweight and highly flexible such that a foot of a wearer may flex in the same manner as if the wearer were barefoot with the puncture-resistant inner sheet protecting the wearer's foot from accidental injury from sharp objects on which the wearer may tread.
Publication WO/2007/101903 presents a footwear piece having an upper made of a first fabric material as well as a sole, which is made of a second fabric material, and that further has a tightening means and a tightening flap.
Publication US 3,863,272 presents an article of footwear comprising a sock of knitted textile material, a sole of flexible material having a fibrous structure selected among the group consisting of velvet-pile fabrics, felt fabrics and tagged carpet fabrics, a molded side portion of plastic material selected among the group consisting of polyvinyl chloride, polyurethane resin and rubber which covers at least part of the periphery of the foot of the sock and the periphery of the sole and attaches the sole to the sock, said part of the periphery of the sock which is covered by the plastic material being knitted in sufficiently close stitches to prevent the penetration of the plastic material through the stitches..
Objective of the invention
The object of the invention is to provide a shoe such as a sports shoe that provides for a barefoot experience but that on the same time is better suited for running and other sport activities than a shoe having a sole completely made of a flexible fabric material. Short description of the invention
The shoe of the invention is characterized by the definitions of independent claim 1. Preferred embodiments of the shoe are defined in the dependent claims 2 to 17.
The invention is based on that the outsole of the shoe comprises a molded part and a protective layer comprising a woven and/or a non-woven sheet that is at least partly covered with rubber or corresponding flexible plastics material. The protective layer is attached to a ground engaging surface of the molded part. The molded part allows for the provision of rigid edges on the outsole while the protective layer provides for good flexibility and can be made thin to provide for the desired barefoot feeling for the user of the shoe. Especially in sport shoes for running the edges of the sole must be made rigid.
In a preferred embodiment of the invention the molded part of the outsole can be considered to form a frame-type structure for the protective layer so that the molded part of the outsole has a ground engaging surface that uniformly and completely surround the protective layer. In this preferred embodiment the molded part forms a frame type structure that has a thicker edge region that forms part of the ground engaging surface of the outsole and that additionally projects upwards from the ground engaging surface of the outsole. This thicker edge region of the molded part of the outsole surrounds a central region of the ground engaging surface of the molded part of the outsole so that the molded part has a thin central region. In this preferred embodiment the protective layer that is made of flexible material is fixedly fastened to the thin central region of the molded part of the outsole at the side of the molded part of the outsole that is in normal use of the shoe turned towards the ground. In a particularly preferable embodiment of the shoe the thin central region is formed by a recess in the surface of the molded part of the outsole that is in normal use of the shoe turned towards the ground. In this preferred embodiment the protective layer that is made of flexible material is fixedly fastened in the recess.
In a preferred embodiment of the invention the upper of the shoe comprises a Strobel sock to which the rest of the upper of the shoe is attached by stitching so that the Strobel sock alone forms the bottom of the upper of the shoe. In this preferred embodiment of the invention the upper of the shoe and the outsole of the shoe are attached so that the Strobel sock is connected with the outsole. In a preferred embodiment of the invention the sole of the shoe will therefore be formed by the Strobel sock of the upper of the shoe and the molded part and the protective layer of the outsole of the shoe and of a possible insole that may be releasably or fixedly fastened inside the inner space of the upper. List of figures
In the following the invention will be described in more detail by referring to the figures, of which
figure 1 shows a preferred embodiment of a shoe according to the invention, figure 2 shows a sectional view of a preferred embodiment of the invention, figure 3 shows the shoe shown in figure 1 seen from below,

Detailed description of the invention
The figure shows an example of a shoe according to the invention.
The shoe comprises an upper 1 forming an inner space for receiving the foot of the wearer, and an outsole 2 attached to the upper 1 and having a ground engaging surface 3.
The outsole 2 comprises a molded part 4 and a protective layer 5.
The protective layer 5 is fixedly fastened to the outside of the molded part 4 so that the protective layer 5 at least partly covers the molded part 4 and so that the protective layer 5 at least partly forms the ground engaging surface 3 of the outsole 2.
The protective layer 5 comprises a woven and/or non-woven sheet that is at least partly covered with rubber or corresponding flexible plastics material. The protective layer 5 can for example comprise a sheet of high strength flexible fibres such as synthetic fibres. The protective layer 5 can for example comprise fibres of aromatic polyamide such as Kevlar® fibers (by DuPont). The protective layer 5 can for example be at least partly made of CeraPrene® UHAR (by Benecke-Kaliko AG, Germany). The protective layer 5 can include synthetic fibers.
The protective layer 5 may be fixedly fastened to the outside of the molded part 4 by an adhesive.
In the shoe shown in the figures the molded part 4 of the outsole 2 forms part of the ground engaging surface 3 of the outsole 2 and the protective layer 5 forms part of the ground engaging surface 3 of the outsole 2.
The thickness of the protective layer 5 is preferably, but not necessarily, between about 0.5 and about 1.5 mm, more preferable about 1 mm.
The molded part 4 comprises preferably, but not necessarily, a recess 6 in which the protective layer 5 is at least partly placed so that the molded part 4 partly forms the ground engaging surface 3 of the outsole 2 and so that the protective layer 5 partly forms the ground engaging surface 3 of the outsole 2. The depth of the recess 6 corresponds preferably, but not necessarily, essentially to the thickness of the protective layer 5. The thickness of the molded part 4 in the area of the recess 6 is preferably, but not necessarily between about 0.5 and about 1.5 mm, more preferable about 1 mm.
In the shoe shown in the figures the molded part 4 of the outsole 2 can be considered to form a frame-type structure for the protective layer 5 so that the molded part 4 of the outsole 2 has a ground engaging surface 3 that uniformly and completely surrounds the protective layer 5. This frame-type structure has an edge region 7 that forms part of the ground engaging surface 3 of the outsole 2 and that surrounds a thin central region 8 of the ground engaging surface 3 of the outsole 2. The protective layer 5 is fixedly fastened to the thin central region 8 of the ground engaging surface 3 of the outsole 2. In the shoe shown in the figures the thin central region 8 is formed by a recess 6 in the molded part 4. In the shoe shown in the figures the molded part 4 of the outsole 2 has an edge region 7 projecting upwards from the ground engaging surface 3 of the outsole 2. The thickness of the edge region 7 of the molded part 4 is preferably, but not necessarily, between about 2 and about 4 mm, more preferable about 3 mm.
The molded part 4 is preferably, but not necessarily, at least partly made of soft flexible plastics material or rubber such as ethylene vinyl acetate (EVA), polyurethane (PU), thermoplastic polyurethane (TPU) or foam rubber.
In the shoe shown in the figures the molded part 4 of the outsole 2 comprises flex groves 9 for providing better flexibility for the molded part 4.
The protective layer 5 is preferably, but not necessarily, essentially free from openings and perforations.
The protective layer 5 is preferably, but not necessarily, essentially planar.
The upper 1 may be made at least partly of Nylon, but can also comprise or be made of other materials such as leather or a mesh structure.
The upper 1 may comprise a Strobel sock 10 that is stitched to the rest of the upper 1. The Strobel sock 10 may be perforated.
The shoe may comprise an insole 12 that may be releasable or fixedly fastened to the rest of the upper 1.
The upper 1 may comprise a heel supporting element 11. The upper 1 may comprise shoelaces 12 or similar means for fastening the shoe to the foot of the wearer when the foot of the wearer is placed in the inner space of the upper 1.
The upper 1 may be laminated to the outsole 2.
In a preferred embodiment of the invention the upper 1 comprises a Strobel sock 10 to which the rest of the upper 1 is attached by stitching so that the Strobel sock 10 alone forms the bottom of the upper 1. In this preferred embodiment of the invention the upper 1 and the outsole 2 are attached so that the Strobel sock 10 is connected with the outsole 2. In a preferred embodiment of the invention the sole of the shoe will therefore be formed by the Strobel sock 10 of the upper 1 and the molded part 4 and the protective layer 5 of the outsole 2 and of a possible insole 12 that may be releasably or fixedly fastened to the rest of the upper 1 inside the inner space of the upper 1.
In a preferred embodiment of the invention the upper 1 comprises a Strobel sock 10 to which the rest of the upper is attached by stitching so that the Strobel sock 10 alone forms the bottom of the upper 1. In this preferred embodiment the Strobel sock 10 is attached to the side the molded part 4 of the outsole 2 that is faced away from the ground engaging surface 3 of the outsole 2. In this preferred embodiment the shoe comprises an insole 12 inside the inner space of the upper 1, which insole 12 covers the Strobel sock 10 inside the inner space of the upper 1. In this preferred embodiment the molded part 4 of the outsole 2 forms part of the ground engaging surface 3 of the outsole 2 and in that the protective layer 5 forms part of the ground engaging surface 3 of the outsole 2. In this preferred embodiment the molded part 4 comprises a recess 6 in which the protective layer 5 is at least partly placed and in that the depth of the recess 6 corresponds essentially to the thickness of the protective layer 5. In this preferred embodiment the protective layer 5 is fixedly fastened to the molded part 4 by an adhesive. In this preferred embodiment the ground engaging surface 3 of the protective layer 5 of the outsole 2 is fully surrounded by the ground engaging surface 3 of the molded part 4 of the outsole 2. In this preferred embodiment the molded part 4 of the outsole 2 has an edge region 7 projecting upwards from the ground engaging surface 3 of the outsole 2. In this preferred embodiment the shoe has a sole that is formed by the Strobel sock 10, the insole 12, the molded part 4 of the outsole 2 and the protective layer 5 of the outsole 2.
It is apparent to a person skilled in the art that as technology advances, the basic idea of the invention can be implemented in various ways. The invention and its embodiments are therefore not restricted to the above examples, but they may vary within the scope of the claims.
