Last, method for manufacturing the last and footwear made from the last

Abstract

Provided are a last for making an article of footwear, an article of footwear that is made from the last and a method for manufacturing the last. The last has dimensions defined by a last length, a joint girth, an instep girth and a heel breadth. In the last, a ratio of the last length to the joint girth is between 0.920 and 0.976, a ratio of the last length to the instep girth is between 0.945 and 1.006, and a ratio of the last length to the heel breadth is between 0.255 and 0.259. The last can provide a shape suitable for comfortably accommodating the elderly foot.

1 . A last for making an article of footwear, wherein the last has dimensions defined by a last length, a joint girth, an instep girth and a heel breadth, wherein a ratio of the last length to the joint girth is between 0.920 and 0.976, a ratio of the last length to the instep girth is between 0.945 and 1.006, and a ratio of the last length to the heel breadth is between 0.255 and 0.259. 
     
     
         2 . The last of  claim 1 , wherein the last defines a space suitable for accommodating a human foot of which a ratio of a ball girth circumference to a foot length is 0.98, a ratio of an instep girth circumference to the foot length is 0.98, and a ratio of a heel breath to the foot length is 0.255. 
     
     
         3 . The last of  claim 1 , wherein the last defines a space suitable for comfortably accommodating a foot of an aged person. 
     
     
         4 . The last of  claim 1 , wherein the ratio of the last length to the joint girth, the ratio of the last length to the instep girth, and the ratio of the last length to the heel breadth of the last are reduced, respectively, as a size of the last increases from size 36 to 44. 
     
     
         5 . The last of  claim 1 , wherein the last length, the joint girth, the instep girth and the heel breadth of the last with a size from 36 to 44 are determined in accordance with respective values represented in  FIG. 3 . 
     
     
         6 . An article of footwear having a shape complimentary to the last of  claim 1 . 
     
     
         7 . The article of footwear of  claim 6 , wherein the last length, the joint girth, the instep girth and the heel breadth of the last with a size from 36 to 44 are determined in accordance with respective values represented in  FIG. 3 . 
     
     
         8 . A method for manufacturing a last for making an article of footwear, wherein the last has dimensions defined by a last length, a joint girth, an instep girth and a heel breadth, the method comprising:
 setting the last length, the joint girth, the instep girth and the heel breadth of the last so that a ratio of the last length to the joint girth is between 0.920 and 0.976, a ratio of the last length to the instep girth is between 0.945 and 1.006 and a ratio of the last length to the heel breadth is between 0.255 and 0.259.   
     
     
         9 . The method of  claim 8 , further comprising:
 setting the last length, the joint girth, the instep girth and the heel breadth of the last so that the ratio of the last length to the joint girth, the ratio of the last length to the instep girth, and the ratio of the last length to the heel breadth of the last are reduced respectively as a size of the last increases from size 36 to 44.   
     
     
         10 . The method of  claim 8 , further comprising:
 setting the last length, the joint girth, the instep girth and the heel breadth of the last with a size from 36 to 44 in accordance with respective values represented in  FIG. 3 .
