Sole of a Shoe

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.

         6 . The sole of  claim 5 , wherein said second outsole toe projection terminates inside of said midsole toe recess when said removably attachable outsole is attached to said shoe. 
     
     
         7 . The sole of  claim 6 , wherein said termination of said second outsole toe projection inside of said midsole toe recess when said removably attachable outsole is attached to said shoe restricts movement between said removably attachable outsole and said midsole in at least one direction. 
     
     
         8 . The sole of  claim 6 , wherein said second outsole toe projection and said midsole toe recess each further comprise mating chamfered edges which mate when said second outsole toe projection terminates inside said midsole toe recess when said removably attachable outsole is attached to said shoe. 
     
     
         9 . The sole of  claim 1 , wherein at least one of the groups consisting of said at least one midsole fastener area and said at least one outsole fastener area further comprises at least one gap. 
     
     
         10 . A sole of a shoe, comprising:
 a midsole further comprising a midsole toe region, a midsole forepart region, and   a midsole heel region;   a first and second removably attachable outsole;   wherein said first and said second removably attachable outsoles are separate;   wherein said first removably attachable outsole has a size and shape which generally matches the size and shape of both said midsole toe and said midsole forepart regions;   wherein said second removably attachable outsole has a size and shape which generally matches the size and shape of said midsole heel region.   
     
     
         11 . The sole of  claim 10 , wherein said midsole further comprises at least one midsole fastener area and wherein said first removably attachable outsole further comprises at least one outsole fastener area which mates with said at least one midsole fastener area when said at first removably attachable outsole is attached to said shoe. 
     
     
         12 . The sole of  claim 11 ,
 wherein said at least one midsole fastener area further comprises at least one groove;   wherein said first removably attachable outsole further comprises at least one bump;   and wherein said at least one bump terminates inside of said at least one groove when said first removably attachable outsole is attached to said shoe.   
     
     
         13 . The sole of  claim 10 , further comprising at least one finger channel in said midsole. 
     
     
         14 . A sole of a shoe, comprising:
 a midsole comprising a midsole forepart region and a midsole toe region;   a first removably 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 bottom surface includes at least two midsole fastener areas separated by at least one midsole forepart gap;   wherein said midsole forepart gap has different physical characteristics from said midsole fastener areas;   wherein said first removably attachable outsole further comprises an outsole contact surface which contacts said midsole bottom surface when said first removably attachable outsole is attached to said shoe;   wherein said outsole forepart region contact surface includes at least two outsole fastener areas that mate with said midsole fastener areas when said first removably attachable outsole is attached to said shoe;   wherein said at least two outsole fastener areas are separated by at least one outsole forepart gap;   wherein said outsole forepart gap has different physical characteristics from said outsole fastener areas.   
     
     
         15 . The sole of  claim 14 , wherein said outsole toe region further comprises an outsole toe projection.
