US Patent:

20200352277, Nov 12, 2020

Filed:

Aug 19, 2019

Appl. No.:

16/544874

Inventors:

Jeffrey Mark Rasmussen - Catonsville MD, US
Jack Stearns Rasmussen - Catonsville MD, US
Corey A. Fleischer - Abingdon MD, US

International Classification:

A43B 13/18

Abstract:

An athlete in any athletic event generates forces on and subjects their lower extremities to forces which are unique to that athlete's mass, speed and strength. These forces are also affected by the composition of the playing field surface, shoe design and construction and other factors. It is possible to determine, according to these factors, the level of force above which injury to the athlete's lower extremities is inevitable—the pre-injury force threshold. This pre-injury force threshold is then used to design and build an athletic shoe which will provide a force-mitigating deformation induced by forces equal to the particular athlete's pre-injury force threshold. This deformation of the athletic shoe prevents injury to the athlete's lower extremities. This deformation may be induced by designing the sole of an athletic shoe with specifically engineered incised cut-outs or channels in the athletic shoe sole.

Abstract:

Each year in North America there are approximately 175,000 non-contact ACL injuries. One of the main causes of these injuries is the rotational and translational forces created when a player makes a sudden change in direction or stops. Every athlete subjects their lower extremities to various forces that are unique to his or her mass, speed, and strength. These forces are affected by composition of the playing field surface, shoe sole design and construction, and other factors. Using these and other factors, the level of force at which injury is inevitable (pre-injury force) is determined and an athletic shoe is created which will provide a mitigating deformation induced by a particular athlete's pre-determined, pre-injury force threshold. A mitigating deformation of as little as 2 degrees can significantly reduce injurious forces. After the athlete has progressed through that particular force-generating movement, the shoe's sole instantly returns to its original shape.
