Abstract
A bowling shoe sole fastening system of structures that allows a variety of outsoles to be attached to and detached from the midsole that improve the consistency of the flex of the show throughout a bowler's stride, which allow the bowling shoe to be adjusted to achieve consistent stopping and sliding characteristics over a variety of bowling lane conditions and maintain consistent performance in the flex of the shoe across cycles of attachment, detachment, and reattachment.
Claims20
A sole of a shoe, comprising:
- a midsole comprising a midsole forepart region, a midsole toe region, a midsole arch region, and a midsole heel region;
- a remove-ably attachable outsole comprising an outsole forepart region and an outsole toe region;
- wherein said midsole further comprises a midsole bottom surface;
- wherein said midsole forepart region further comprises a midsole forepart region bottom surface and a midsole fastener area;
- wherein said midsole forepart region bottom surface and said midsole fastener area are made of different materials;
- wherein a finger channel extends through a portion of said midsole heel region
- wherein said remove-ably attachable outsole further comprises an outsole contact surface which contacts said midsole bottom surface from a front of said midsole toe region to a front of said midsole arch region when said remove-ably attachable outsole is attached to said shoe;
- wherein said outsole contact surface further comprises a contact area which contacts said midsole forepart region bottom surface when said remove-ably attachable outsole is attached to said shoe and an outsole fastener area that mates with said midsole fastener area when said remove-ably attachable outsole is attached to said shoe;
- wherein said midsole fastener area is further comprised of a hook fastener area and a midsole fastener area gap;
- wherein said midsole fastener area gap is a flat midsole gap and said outsole fastener area has an outsole fastener gap and said outsole fastener gap presses against said midsole fastener area gap;
- wherein said outsole forepart is further comprised of a pile fastener area;
- wherein said remove-ably attachable outsole has an outsole toe ridge which generally projects perpendicular to said outsole and covers at least a part of said midsole toe region;
- wherein said midsole toe region is elevated from said midsole forepart region;
- wherein said midsole toe region and said midsole forepart region are on different planes;
- wherein said midsole toe region and said midsole forepart region have different thicknesses.

- wherein said midsole further comprises a midsole toe edge;
- wherein said midsole toe edge is formed with a notched edge;
- and
- wherein said midsole fastener area is further comprised of a hook fastener area of the midsole and said outsole fastener area is further comprised of a pile fastener area;
- wherein said outsole toe ridge is formed using a rigid material;
- wherein said notched edge has a notch depth extending away from said midsole toe edge;
- wherein said midsole toe region is elevated from said midsole forepart region;
- wherein said midsole toe region and said midsole forepart region are on different planes;
- wherein said midsole toe region and said midsole forepart region have different thicknesses.
