Fluid flow system for spring-cush |
摘要 |
A fluid flow system for a spring-cushioned shoe is disclosed. The sole of the shoe includes a vacuity, a spring disposed within the vacuity, and a fluid passageway in fluid communication with the vacuity. The fluid flow passageway allows fluid, such as air, to escape the vacuity when the volume of the vacuity is reduced during a foot strike.
