Description

RELATED APPLICATIONS

[0001] This application claims priority of U.S. application Ser. No. 61/894,353, filed on Oct. 22, 2013, titled ATHLETIC SHOE TRAINER, which application is incorporated in its entirety by reference in this application.

BACKGROUND INFORMATION

[0002] 1. Field of Invention

[0003] The invention relates generally to an athletic shoe, and in particular, an athletic shoe trainer having an elevated midsole to simulate training in running spikes.

[0004] 2. Background

[0005] High performance athletic sprinters often suffer from injuries or chronic pain in the lower leg, e.g., shin splints. It is hypothesized that this is due to sprinters not having access to footwear that provides conditioning that accurately simulates the later season training and competition in sprinting spikes. This gap can be attributed to the fact that competitive spike shoes possess key functional features not incorporated into typical training flats. Specifically, he spike shoe places the heel in an elevated position and also typically incorporates a common feature known as a "spike plate" which limits flexibility in the arch of the foot. In order to prevent these injuries, sprinters must gradually incorporate spike shoes into their training regimen. Often training facilities that are available for early season conditioning do not permit spike training.

[0006] Thus, a need exists for an athletic shoe that Allows for speed and power training in true sprint form on all indoor surfaces and, further, Provides conditioning of lower leg muscles and transition from traditional running shoes ("flats") to running spikes ("spikes").

SUMMARY

[0007] An athletic shoe is provided to simulate training in running spikes. The athletic shoe includes an outsole for engaging a horizontal supporting surface, a midsole having a wedge portion coupled to the outsole and an arch portion elevated at an angle of not less than 15.degree. relative to the horizontal surface; and an upper that encloses the midsole. By incorporating a wedge that elevates the forefoot of the shoe and a molded plate (i.e., the arch portion), rigidity is provided to the arch of the foot which forces the user to run on the ball of the user's feet. The outsole also facilitates optimum support and force transfer via integrated bands and a Velcro.RTM. strap that runs over the laces.

[0008] In one example, the athletic shoe may include an outsole for engaging a supporting horizontal surface and a midsole coupled to the outsole, where the midsole includes an arch portion elevated at an angle of not less than 15.degree. relative to the horizontal surface. The athletic shoe also includes an upper that encloses the midsole.

[0009] In another example, the athletic shoe may include an outsole having a planar gripping surface designed to engage in planar contact with a supporting horizontal surface, and a midsole coupled to the outsole, where the midsole includes an arch portion elevated at an angle of not less than 15.degree. relative to the horizontal surface. The athletic shoe further includes an upper that encloses the midsole.

[0010] In yet another example, the athletic shoe may include an outsole and a midsole coupled to the outsole, where the midsole includes a first portion and a second portion elevated at an angle of not less than 15.degree. relative to the first portion. The athletic shoe further includes an upper that encloses the midsole.
