Shoe having an outsole with bonded fibers
Provided is a shoe having a bottom surface that is adjacent to the ground in normal use. A sole, which is sufficiently durable and/or strong for long-term outdoor use, forms at least a portion of the bottom surface, and an upper portion extends above the sole. A plurality of small material particles are bonded to at least a portion of the bottom surface of the shoe.
1. A shoe comprising:
(a) an outsole that is adjacent to the ground in normal use;
(b) an upper portion extending above the outsole; and
(c) a thin sheet of material bonded to, or forming a part of, the outsole,
wherein a plurality of individual fabric fibers are directly bonded to said sheet of material with an adhesive material,
wherein the outsole is sufficiently durable for long-term outdoor use, and
wherein the outsole includes indentations and each of the plurality of indentations is predominantly uncoated with said fabric fibers.
2. A shoe according to claim 1 , wherein at least 1,000 fabric fibers are bonded to the sheet of material.
3. A shoe according to claim 1 , wherein the sheet of material is bonded to the outsole using adhesive material.
4. A shoe according to claim 1 , wherein the sheet of material is bonded to the bottom surface of the shoe using at least one of heat and pressure.
5. A shoe according to claim 1 , wherein at least a majority of the fabric fibers are bonded to the sheet of material at a right angle.
6. A shoe according to claim 1 , wherein the outsole has an ASTM-D624 tear resistance of at least 6 kilograms per centimeter.
7. A shoe according to claim 1 , wherein the outsole has an ASTM-D624 tear resistance of at least 9 kilograms per centimeter.
8. A shoe according to claim 1 , wherein the outsole has an ASTM-D624 tear resistance of at least 15 kilograms per centimeter.
9. A shoe according to claim 1 , wherein the outsole has an ASTM-D1630(NBS) abrasion resistance of at least 25%.
10. A shoe according to claim 1 , wherein the outsole has an ASTM-D1630(NBS) abrasion resistance of at least 35%.
11. A shoe according to claim 1 , wherein the outsole has an ASTM-D1630(NBS) abrasion resistance of at least 45%.
12. A shoe according to claim 1 , wherein the outsole is comprised of at least one of leather, natural rubber and synthetic rubber.
13. A shoe according to claim 1 , wherein with the fabric fibers cover substantially all of that portion of the outsole that normally comes into contact with the ground.
14. A shoe according to claim 1 , wherein the outsole includes indentations and each of the plurality of indentations is predominantly uncoated with said fabric fibers.
15. A shoe according to claim 1 , wherein at least 10,000 fabric fibers are bonded to the sheet of material.
16. A shoe according to claim 1 , wherein the sheet of material is comprised of at least one of: fabric, ethylene vinyl acetate (EVA), polyvinyl chloride (PVC) or thermoplastic rubber (TPR).
17. A shoe according to claim 1 , wherein the sheet material has been molded together with the shoe's outsole.
18. A shoe according to claim 1 , wherein a plurality of pieces of sheet material, each piece having a plurality of fabric fibers bonded to it, are applied to different locations on the bottom surface of said shoe.
19. A shoe according to claim 1 , wherein the fabric fibers are natural fibers.
