Patent 10111492 was granted and assigned to Nike, Inc. on October, 2018 by the United States Patent and Trademark Office.
An article of footwear that offers different levels of cushioning and support depending on the direction of force applied to the midsole. An outer edge of the midsole includes an inwardly-extending elongate groove with a V-shaped cross-sectional configuration. An elongate insert having a V-shaped cross-sectional configuration is secured to the elongate groove. The insert forms a spring that dynamically alters the character of the support provided by the footwear to a foot of a wearer during “banking” or side-to-side movement.
