Pair of athletic shoes with asymmetric support between the uppers of the pair

Abstract

A pair of shoes is provided that includes a left and a right shoe. The left shoe includes an upper having a left forefoot portion, the left forefoot portion having a lateral side with a portion thereof made of a first material and a medial side with a portion thereof made of a second material. The right shoe includes an upper having a right forefoot, the right forefoot having a medial side with a portion thereof made of the first material and a lateral side with a portion thereof made of the second material, wherein one of the first material and the second material provides more support than the other. The more supportive first material can include a polyurethane, such as TPU, a non-stretch synthetic material, or ceraprene. The second, less supportable material can be a light weight breathable mesh.

Description

[0001]This patent application claims priority to the provisional patent application Ser. No. 61 / 210,283, entitled “Pair of Athletic Shoes with Asymmetric Support Between the Uppers of the Pair,” filed on Mar. 16, 2009, the entirety of which is incorporated herein by reference.TECHNICAL FIELD[0002]The present invention relates to athletic footwear. In particular, the present invention relates to athletic shoes having an improved upper used in sports that entail asymmetric movement of the feet, for example, track running.BACKGROUND OF THE INVENTION[0003]Athletic footwear must provide stable and comfortable support for the foot. Specifically, it is important that the footwear be comfortable while providing adequate support during various foot movements associated with athletic activity.

AI Technical Summary

Benefits of technology

"The present invention provides a pair of athletic shoes designed for sports involving asymmetric foot movements, such as banked track running. The shoes are optimized for flexibility, balance control, propulsion, stability, and support in specific areas to improve performance and minimize injuries. The shoes have a left and right shoe with different materials on the forefoot to provide asymmetrical support. The less supportive material is a light weight breathable mesh, while the more supportive material can include polyurethane, non-stretch synthetic material, or ceraprene. The technical effects of the invention include improved performance, reduced injuries, and better comfort during training and events."

Problems solved by technology

Though this material may be comfortable, it often does not provide adequate support for an athlete.

In addition, while a pair of shoes of any type typically includes a right shoe that is a mirror image of the left shoe in order to provide the same functionality to corresponding portions of each foot, this is not optimal for sports that require asymmetrical foot movement, such as track running.
