Abstract: A resilient sole for use in an article of footwear. The sole has controlled stiffness and manifests a slow shape recovery following compression by the plantar surface of the foot. A footwear construction using a sole with such characteristics improves stability of users of all age groups, while enhancing comfort.

Abstract: A device for connecting a cycling shoe to the crank arm of a bicycle which allows rapid changes in the shoe position relatively to the pedal pivot axis without the necessity of physically disconnecting the cycling shoe from the bicycle. The device comprises a first member for rotational connection to the crank arm about the pedal pivot axis and a second member for connection to the sole of a cycling shoe, the members being in a mutual engagement permitting transmission of pedalling efforts to the crank arm and also allowing a translatory motion of one member relatively to the other. A lock is provided between the members for normally blocking a translatory motion therebetween. The lock is releasable upon rotation of one member relatively to the other, whereby permitting longitudinal repositioning of the cycling shoe with respect to the pedal pivot axis.
