Method for shaping shoe spikes

Abstract

A method for shaping shoe spikes is disclosed herein, wherein the distribution of the spikes is divided into five areas, including an inside stepping out area, a thumb ball stepping area, a base area, a feedback area and an outside landing area. The spike of the outside landing area has a height less than that of a spike of the base area so that the stress resulted from foot running can be guided to the thumb ball stepping area from the outside landing area. Furthermore, the spikes of the thumb ball stepping area are shaped to be on the same tread surface and contacted with the ground at the same time so that the stress while foot running can be undertaken by the thumb ball stepping area to guide the sufficient explosive force to the inside stepping out area and further output from the inside stepping out area.

What is claimed is: 
     
         1 . A method for shaping shoe spikes distributed on an inside stepping out area corresponding to a foot thumb, a thumb ball stepping area corresponding to a thumb ball, a base area, a feedback area, and an outside landing area, comprises the steps of:
 (a) reserving a height of the spike of the base area and taking the same as a basis reference;   (b) shaping the spike of the outside landing area to have a height less than that of the spike of the base area in accordance with a stress guided path while foot running;   (c) shaping the spikes of the thumb ball stepping area to be on a same tread surface and contacted with the ground at the same time according to the stress guided path from the base area to the thumb ball stepping area; and   (d) forming an inclination angle between the spike of the feedback area and the spike of the thumb ball stepping area as the feedback area is subject to the stress guided path, so as to allow the stress guided path to be guided from the feedback area to the thumb ball stepping area and output from the thumb ball stepping area to the inside stepping out area.   
     
     
         2 . As the method claimed in  claim 1 , wherein the height of the spike of the outside landing area in step (b) ranges from 2 mm to 3 mm in case of two spikes located on the outside landing area. 
     
     
         3 . As the method claimed in  claim 1 , wherein the inclination angle in step (d) ranges from 3 to 5 degrees relative to a horizontal line.
