Method Of Customizing Stability In Articles Of Footwear

The disclosed method provides a way to manufacture a style of an article of footwear in bulk, while providing customization for heel stability for individual customers. Moreover, the disclosed method provides a way to customize articles of footwear for a customer on an ongoing basis, such that the heel stability of the articles of footwear is refined until a tailored fit is achieved for the same customer. Generally, the method may include providing a user/customer with an article of footwear, getting evaluation information about the stability of the article of footwear from a survey (e.g., asking the user to rate the stability of the article of footwear in a smartphone app), modifying the next article of footwear provided to the user/customer according to the evaluation information, and iterating through this process to give the user an article optimized for stability.

Methods of manufacturing articles utilizing foam particles

Methods for manufacturing articles of footwear are provided. In various aspects, the methods comprise utilizing additive manufacturing methods with foam particles. In some aspects, the additive manufacturing methods comprise increasing the temperature of a plurality of foam particles with actinic radiation under conditions effective to fuse a portion of the plurality of foam particles comprising one or more thermoplastic elastomers. Increasing the temperature of the foam particles can be carried out for one or multiple iterations. The disclosed methods can be used to manufacturer articles with sub-regions that exhibit differing degrees of fusion between the foam particles, thereby resulting in sub-regions with different properties such as density, resilience, and/or flexural modulus. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

Self-recovering impact absorbing footwear

An impact absorbing footwear device employs opposed planar sole portions engaged by a selective resistance coupling that biases the opposed planar sole portions in a non-linear manner in response to forces exerted by the wearer against the sole portion in frictional contact with a floor surface. The planar sole portions are disposed in a footwear appliance that takes the form of an athletic shoe sole. The selective resistance coupling includes a plurality of resilient deformation members that engage the planar sole portions in an opposed circumferentially aligned manner, selectively deform in response to pressure exerted by the wearer for preventing ACL and other impact related injuries, and recover to an undeformed rest position without breakaway to allow the wearer uninterrupted usage while dampening forces that surpass an injury threshold from the resilient deformation that allows the planar sole portions to temporarily misalign.

Shoe

A shoe (A) provided with an internal side (LI) and an external side (LE) and comprising a sole (I), an intermediate sole (3) and a reinforcement insert (4) joined with the intermediate sole (3) and comprising at least one lateral wing (42,43) which is inclined and disposed on the internal side (LI) or the external side (LE) of the shoe (A).

Golf shoe having composite plate in midsole for providing flex and stabti jty
11425959 · 2022-08-30 · ·

Golf shoes having improved constructions are provided. The golf shoes include upper, midsole, and outsole sections. The upper may be made of a soft, breathable leather material. The midsole includes an upper region formed from a first material such as a foamed ethylene vinyl acetate (EVA); and a lower region formed from a second material such as a foamed ethylene vinyl acetate (EVA), wherein the materials have different hardness levels. A fiber-reinforced composite plate such as, for example, a carbon fiber plate is disposed in the midsole. The outsole contains different traction members arranged in a precise geometric structure that helps provide improved stability and traction.

SOLE STRUCTURE FOR AN ARTICLE OF FOOTWEAR WITH SIDE WALL NOTCH AND NONLINEAR BENDING STIFFNESS
20170224051 · 2017-08-10 · ·

A sole structure for an article of footwear comprises a sole plate that includes a forefoot portion with a foot-facing surface. The sole plate has at least one side wall extending upward from the foot-facing surface. The at least one side wall has a first notch in an upper periphery of the side wall in the forefoot portion. The first notch is configured to be open when the forefoot portion of the sole plate is dorsiflexed in a first portion of a flexion range and closed when the forefoot portion of the sole plate is dorsiflexed in a second portion of the flexion range greater than the first portion.
