A device configured to surround a portion of a foot-receiving cavity at a heel region of an article of footwear comprises a control bar having a center segment, a first side arm extending from the center segment, and a second side arm spaced from the first side arm and extending from the center segment. The control bar may include a series of slats. A base supports the control bar and is connected to the first side arm and the second side arm. The control bar is biased to an unstressed position with the center segment a first distance from the base, and elastically bends under an applied force to a loaded position with the center segment a second distance from the base less than the first distance. The device stores potential energy that returns the control bar to the unloaded position upon removal of the applied load.

Footwear heel spring device

Articles of footwear include upper components and/or sole components. In some examples, the articles of footwear and/or sole structures may include features making them well suited for obstacle course type athletic events (e.g., by providing enhanced traction for various obstacle course events, such as wall climb events, rope climb events, etc.). As some more specific examples, articles of footwear and/or components thereof may include one or more of: (a) a ground-contacting surface having a plurality of large grooves, a plurality of small grooves, and relatively flat and/or smoothly curved base surfaces between the grooves; (b) a medial sidewall having a concave exterior surface, e.g., in the midfoot area; (c) a medial sidewall having enhanced traction features, e.g., in the midfoot area; and/or (d) a medial instep component (e.g., medial eye stay reinforcing component) having enhanced traction features.

Articles of footwear and upper and/or sole components therefor

Shoe

An article of footwear includes a footwear upper defining at least a portion of an ankle opening and including a flexible covering, a sole structure secured to and underlying the footwear upper, and a device including a control bar and a base. The control bar includes a center segment rearward of the ankle opening, a first side arm extending downwardly and forwardly from the center segment at a medial side of the footwear upper, and a second side arm extending downwardly and forwardly from the center segment at a lateral side of the footwear upper. The base is connected to both of the first side arm and the second side arm such that the center segment, the first side arm, the second side arm, and the base define a void therebetween. The flexible covering extends across the void.

A traction system for an ambulatory support such as a prosthetic foot blade or a crutch includes a sole plate, a latch assembly, and a strap. The sole plate is couplable to a distal end of the ambulatory support to extend under a bottom side of the ambulatory support and a latch assembly. The latch assembly includes a front catch and a rear catch both fixable at a top side of the ambulatory support with the front catch nearer to the distal end of the ambulatory support than the rear catch, and a lever having a front end and a rear end, the front end releasably latchable to the front catch and the rear end releasably latchable to the rear catch when the lever is pivoted about the latched front end. The strap is secured to the lever and to the sole plate.
