Athletic shoe with Y support |
摘要 |
An athletic shoe employs a pair of spring structures in such a way that an arm of a Y-shaped spring on one side of the ankle fastens under tension to a corresponding arm of a spring on the other side of the ankle. The springs are preferably of sheet material conforming to and affixed to the upper. The two springs may be formed as a wrap-around single member.
