Footwear with a removable outsole

Abstract

A footwear apparatus may include an upper portion that includes multiple layers. At least one of the layers may be an attachment layer that includes multiple holes. An outsole may include multiple fasteners that are positioned to align with the holes of the attachment layer. Furthermore, the insertion of the fasteners of the outsole into the holes of the attachment layer may attach the outsole to the upper portion of the footwear apparatus.

         2 . The footwear apparatus of  claim 1 , wherein the plurality of layers of the upper portion further comprises a midsole and an insole. 
     
     
         3 . The footwear apparatus of  claim 2 , wherein each of the midsole and the insole comprises a plurality of holes that correspond to the plurality of holes of the attachment layer. 
     
     
         4 . The footwear apparatus of  claim 3 , wherein the attachment layer is coupled to a bottom of the midsole and the insole is coupled to a top of the midsole. 
     
     
         5 . The footwear apparatus of  claim 3 , wherein the plurality of holes of the midsole, insole, and attachment layer are vertical. 
     
     
         6 . The footwear apparatus of  claim 3 , wherein a first portion of the plurality of holes of the midsole, insole, and attachment layer are vertical, and wherein a second portion of the plurality of holes of the midsole, insole, and attachment layer are angled. 
     
     
         7 . The footwear apparatus of  claim 6 , wherein the second portion of the plurality of holes are located at a perimeter of the midsole, insole, and the attachment layer, and wherein the first portion of the plurality of holes are located in an interior of the midsole, insole, and the attachment layer. 
     
     
         8 . The footwear apparatus of  claim 6 , wherein the angle of the second portion of the plurality of the holes is towards a heel of the footwear apparatus. 
     
     
         9 . The footwear apparatus of  claim 1 , wherein the attachment layer is a low density polyethylene material (LDPE). 
     
     
         10 . The footwear apparatus of  claim 1 , wherein the plurality of fasteners are exposed at an insole of the footwear apparatus when the fasteners of the outsole are inserted into the plurality of holes of the attachment layer. 
     
     
         11 . The footwear apparatus of  claim 10 , wherein the outsole is removable from the attachment layer in response to a force applied against the plurality of fasteners when the plurality of fasteners are inserted into the plurality of holes of the attachment layer. 
     
     
         12 . The footwear apparatus of  claim 11 , wherein the outsole is removable from the attachment layer in response to the force applied against a top of the plurality of fasteners through an insole of the footwear apparatus. 
     
     
         13 . A shoe comprising:
 an insole comprising a first plurality of cavities;   a midsole comprising a second plurality of cavities and coupled to a bottom of the insole;   an attachment layer comprising a third plurality of cavities and coupled to a bottom of the midsole; and   an outsole comprising a plurality of fasteners, wherein the plurality of fasteners are to attach the outsole to the insole, the midsole, and the attachment layer in response to an insertion of the plurality of fasteners through the first, second, and third pluralities of cavities.   
     
     
         14 . The shoe of  claim 13 , further comprising:
 an insert placed over the insole, wherein the insert does not comprise any cavities, and wherein the insert covers a plurality of tops of the plurality of fasteners through the insole when the outsole is attached to the insole, the midsole, and the attachment layer.   
     
     
         15 . The shoe of  claim 14 , wherein after the attachment of the plurality of fasteners, the outsole is removable in response to a force against the top of the plurality of fasteners. 
     
     
         16 . The shoe of  claim 13 , wherein the outsole further comprises an orthopedic sole. 
     
     
         17 . The shoe of  claim 13 , wherein the outsole further comprises a sports sole. 
     
     
         18 . The shoe of  claim 13 , wherein the first, second, and third pluralities of cavities are angled towards a heel of the shoe. 
     
     
         19 . The shoe of  claim 13 , wherein each of the plurality of fasteners comprises a column and a first fastening portion and a second fastening portion, wherein the first fastening portion is attached to the column above the second fastening portion. 
     
     
         20 . An apparatus comprising:
 an outsole associated with footwear, wherein the outsole comprises a plurality of fasteners that are positioned to align with a plurality of holes associated with an upper portion of the footwear, wherein the plurality of fasteners are further positioned so that an insertion of the fasteners of the outsole into the plurality of holes of the upper portion of the footwear attaches the outsole to the upper portion.
