Cycling shoe with slow-rebound nanofoam

Abstract

A cycling shoe including an upper part configured to receive a foot of a user, an outsole disposed on a bottom of the cycling shoe, and a midsole disposed between the upper part and the outsole, the midsole including a nanofoam and having a hardness between 45 D and 65 D, inclusive, as measured by a durometer.

1 . A cycling shoe comprising:
 an upper part configured to receive a foot of a user;   an outsole disposed on a bottom of the cycling shoe; and   a midsole disposed between the upper part and the outsole, the midsole comprising a nanofoam and having a hardness between 45 D and 65 D, inclusive, as measured by a durometer.   
     
     
         2 . The cycling shoe of  claim 1 , wherein the upper shoe comprises an insole disposed above the midsole. 
     
     
         3 . The cycling shoe of  claim 2 , wherein the insole comprises an ethylene vinyl acetate (EVA) foam. 
     
     
         4 . The cycling shoe of  claim 3 , wherein the insole is constructed by injection molding the EVA foam. 
     
     
         5 . The cycling shoe of  claim 1 , wherein the midsole is constructed by injection molding the nanofoam. 
     
     
         6 . The cycling shoe of  claim 1 , wherein midsole comprises a die cut sheet of nanofoam. 
     
     
         7 . The cycling shoe of  claim 1 , wherein the nanofoam comprises pores having a diameter of less than 100 nanometers. 
     
     
         8 . The cycling shoe of  claim 1 , wherein the midsole has a hardness between 50 D and 60 D, inclusive, as measured by a durometer. 
     
     
         9 . The cycling shoe of  claim 8 , wherein the midsole has a hardness between 54 D and 56 D, inclusive, as measured by a durometer. 
     
     
         10 . The cycling shoe of  claim 9 , wherein the midsole has a hardness of 55 D as measured by a durometer. 
     
     
         11 . The cycling shoe of  claim 1 , wherein the upper part comprises a microfiber material. 
     
     
         12 . The cycling shoe of  claim 1 , wherein the outsole comprises a rubber material. 
     
     
         13 . The cycling shoe of  claim 1 , wherein the midsole comprises a honeycombed nanofoam structure. 
     
     
         14 . The cycling shoe of  claim 1 , wherein the midsole comprises a grooved nanofoam structure. 
     
     
         15 . The cycling shoe of  claim 1 , wherein the midsole comprises a raised perimeter. 
     
     
         16 . A cycling shoe comprising:
 an upper part configured to receive a foot of a user;   an outsole disposed on a bottom of the cycling shoe; and   a midsole disposed between the upper part and the outsole, the midsole comprising a nanofoam and having a hardness between 55 D and 60 D, inclusive, as measured by a durometer.   
     
     
         17 . A cycling shoe comprising:
 an upper part configured to receive a foot of a user;   an outsole disposed on a bottom of the cycling shoe; and   a midsole disposed between the upper part and the outsole, the midsole comprising a nanofoam and having a hardness between 55 D and 60 D, inclusive, as measured by a durometer, wherein the midsole comprises a raised perimeter.
