Upper of football shoe and football shoes using the upper

Abstract

Provided is a first cushioning material layered between an outer portion and an inner portion, and extending linearly from a forward position of a forefoot F of a wearer of a shoe, through a position corresponding to an MP joint at least on a medial side of the wearer's foot, toward a position rearward of the MP joint. The first cushioning material is configured such that a line width of a rearward cushioning portion in a direction orthogonal to the longitudinal direction is greater than a line width of a forward cushioning portion.

What is claimed is: 
     
         1 . An upper of a football shoe, the upper including an upper body, wherein
 the upper body includes an outer portion disposed on an outer side of the shoe and an inner portion layered on an inner side of the outer portion,   the upper body is provided with a first cushioning material layered between the outer portion and the inner portion, and extending linearly from a forward position of a forefoot F of a wearer of the shoe, through a position corresponding to an MP joint at least on a medial side of the wearer's foot, toward a position rearward of the MP joint,   the first cushioning material includes
 a forward cushioning portion disposed in a forward region, of the upper, located forward of the position corresponding to the MP joint, and 
 a rearward cushioning portion disposed in a rearward region, of the upper, continuous with the forward cushioning portion and located rearward of the position corresponding to the MP joint, and 
   the rearward cushioning portion is configured such that a line width in a direction orthogonal to a longitudinal direction of the first cushioning material is greater than a line width of the forward cushioning portion.   
     
     
         2 . The upper of  claim 1 , wherein
 the first cushioning material is configured such that the line width gradually increases from a forward position of the forefoot on the medial side toward a rear end.   
     
     
         3 . The upper of  claim 1 , wherein
 the first cushioning material is configured such that the line width of a front end of the forward cushioning portion is half or less of the line width of a rear end of the rearward cushioning portion.   
     
     
         4 . The upper of  claim 1 , wherein
 the rearward cushioning portion has a greater thickness than the forward cushioning portion.   
     
     
         5 . The upper of  claim 1 , wherein
 the first cushioning material includes a plurality of first cushioning materials, and   the plurality of first cushioning materials are arranged so as to be apart from one another in a direction intersecting with the longitudinal direction.   
     
     
         6 . The upper of  claim 5 , further comprising:
 a second cushioning material layered between the outer portion and the inner portion and extending linearly so as to intersect with the plurality of first cushioning materials, wherein   the second cushioning material is formed integrally with each of the first cushioning materials.   
     
     
         7 . The upper of  claim 1 , further comprising:
 a plurality of third cushioning materials disposed on a lateral side, layered between the outer portion and the inner portion, and extending linearly, wherein   the third cushioning materials are disposed at different positions from the first cushioning material.   
     
     
         8 . The upper of  claim 7 , wherein
 a reinforcing material configured to reinforce the upper layered at least between each of the third cushioning materials and the outer portion or between each of the third cushioning materials and the inner portion.   
     
     
         9 . A football shoe comprising the upper of  claim 1 . 
     
     
         10 . A football shoe comprising the upper of  claim 2 . 
     
     
         11 . A football shoe comprising the upper of  claim 3 . 
     
     
         12 . A football shoe comprising the upper of  claim 4 .
