Benefits of technology

The present invention relates to an athletic shoe with a reactive midsole that creates a dynamic offset between a heel center of pressure and a ball-of-foot center of pressure, providing a smoother and more efficient running experience. The midsole comprises a first portion adjacent the heel and a second portion of decreasing thickness, with the first portion being of equal or less total distance than the longitudinal axis of the midsole. The foot center of pressure imparted to the midsole continuously increases between the loading gait phase and the toe off gail phase. This design can be used in various athletic activities where improved performance, comfort, and / or increased efficiency is desired.

Problems solved by technology

However, the conventional designs do not appreciably if at all influence the loading dynamics of a runner's heel center of pressure and a ball-of-foot center of pressure, or combinations thereof, during the phases of engagement with the ground.

example

[0095]Without intending to limit the scope of the invention, Example A1-A13 depicts one example construction of one embodiment of the invention in drawings each to scale. Dimensions are in millimeters.

[0096]Examples A1-A3 depicts respective lateral, bottom, and medial views of the outsole / midsole portion of one embodiment of the invention. Examples A5-A6 depict respective toe and heel views of the outsole / midsole of Examples A1-3. Example A4 depicts a generally longitudinal cross-sectional view along axis Section A-A′ of Example A2. Examples A7-A12 depict sequential cross-sectional views of insole / midsole of Examples A1-3.

[0097]Note different materials and different geometries of Examples A7-A12. For example, the material of upper left to lower right cross-section markings (the dominant material of Example A7) is of a first material (here, CMEVA), the material with lower left to upper right cross-section markings (the mid-upper portion of Example A7) is of a second material (here, V...

Abstract

This invention relates generally to footwear and methods for making the same, and more particularly to an athletic shoe with a reactive midsole. In one aspect of the invention, the midsole provides a continuously increasing offset between a heel center of pressure and a ball-of-foot center of pressure between the loading and a toe off gait phases.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Patent Application No. 61 / 684,563, entitled “REACTIVE SHOE” filed on Aug. 17, 2012, the entire disclosure of which is incorporated by reference herein. This application also cross-references the following U.S. Design patent application Ser. Nos. 29 / 428,044, 29 / 428,045, 29 / 428,047, 29 / 428,049, 29 / 428,051 and 29 / 428,052, all filed Jul. 25, 2012 and all entitled “Shoe Sole,” the entire disclosures of which are all incorporated by reference herein.FIELD[0002]This disclosure relates to a midsole for footwear, more particularly to a reactive midsole having a dynamic offset.BACKGROUND[0003]Athletic footwear ideally provides protection from injury while enhancing performance. Generally, athletic footwear comprises an upper portion and a sole portion. The upper portion at minimum secures the footwear to the user's foot and attaches to the sole. The sole traditionally comprises a midsole and a...
