Problems solved by technology

A highly cushioned sole, designed to compress and efficiently absorb significant impact forces, may not provide sufficient foot support, and this may lead to premature foot fatigue.
Such a cushioned sole also might not allow a proper distribution of forces along the bottom of the foot during a gait cycle, which can lead to an erratic torsional, lateral, or lengthwise twisting or rotation of the foot, which can be deleterious to the gait of the wearer.
On the other hand, an overly fir

Example

[0026]A current embodiment of the footwear is illustrated in FIGS. 1-7, and generally designated 10. In these embodiments, the improved article of footwear includes a sole assembly configured to provide benefits in impact attenuation, foot motion, and energy return.

[0027]Although the current embodiment of footwear is illustrated in the context of a performance shoe, it may be incorporated into any type or style of footwear, including casual shoes, trail shoes and boots, hiking shoes, work boots, all-terrain shoes, barefoot running shoes, athletic shoes, running shoes, sneakers, conventional tennis shoes, walking shoes, multisport footwear, boots, dress shoes or any other type of footwear or footwear components. It also should be noted that directional terms, such as “vertical,”“horizontal,”“top,”“bottom,”“upper,”“lower,”“inner,”“inwardly,”“outer”, “outwardly,”“below” and “above” are used to assist in describing the embodiments based on the orientation of the embodiments shown in the...

Abstract

A sole assembly is provided including multiple compression units entrapped in a midsole and adjacent an outsole to efficiently distribute forces and to assist in correct foot motion during a gait cycle. The multiple compression units can be linked to one another to assist the foot in moving through an appropriate foot motion during a gait cycle. A heel compression unit can be linked to an arch compression unit, which can be linked to one or more forefoot compression units, which can be linked to a toe compression unit. The linking of the heel compression unit, the arch compression unit, and the forefoot compression unit to one another can resist torsional movement of the units between one another, thereby providing a more stable foot support, while still providing impact-attenuation and force distribution through the sole assembly.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to footwear, and more particularly to a sole assembly for footwear.[0002]There are a variety of footwear constructed for efficient function in different activities. Many footwear are designed to provide a high level of stable support, coupled with impact attenuation upon engagement with an underfoot surface, such as the ground. Much of the support and impact protection afforded by footwear is attributable to the configuration of the sole. The sole protects the foot by dispersing significant forces caused by running, jumping, training and even walking. The sole also provides cushioning that absorbs impact and protects the wearer's appendages, such as their feet, ankles and knees, from the stress associated with strenuous and even day-to-day activities. At the same time, the sole plays a role in helping support the foot in its proper shape to prevent a wearer's feet and legs from becoming fatigued over time.[0003]The objec...
