A shoe sole includes a body portion and a heel holding portion. The heel holding portion is located opposite to a ground contact surface of the body portion and holds a heel portion of a foot at least from a medial foot side. The body portion includes a low hardness portion and a high hardness portion. The high hardness portion is a foam material harder than a foam material of the low hardness portion. The heel holding portion is a resin harder than the foam material of the low hardness portion and the foam material of the high hardness portion. On the medial foot side in a rear foot portion, the low hardness portion is located between the heel holding portion and the high hardness portion in an up-down direction.

An article of footwear includes an upper and a midsole coupled with the upper. The midsole includes at least a portion of a solid resilin material comprising a cross-linked recombinant resilin and a polar nonaqueous solvent.

A footwear article includes a tongue and a tongue reinforcer, which helps the tongue maintain a shape and position when the tongue is subjected to forces or adjustments, such as from other footwear-article elements or from a wearer. For example, the tongue reinforcer may help the tongue maintain a shape and position when a wearer is inserting his or her foot into the footwear article or when medial and/or lateral quarters press inward on the tongue.

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.

A footwear article is provided herein. The footwear article may include a sole coupled to a cord structure. The cord structure may include interconnected bights in a vamp cord and a rand cord forming a loop line extending along at least a portion of the footwear article.

A lace guide for an article of footwear comprises a base, a body protruding from the base, and an enlarged head at a distal end of the body. The body, the base, and the enlarged head define an external channel that extends at least partially around the body to receive and retain a lace. The base may be a heel counter, and the lace guide and the heel counter may be an integral, one-piece component. Alternatively, the base of the lace guide may be a wing extending along a side of the upper, or may be secured to a footwear upper.

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.

An article of footwear includes an upper and a U-shaped foamed ankle collar. The ankle collar may form the topmost region of the foot receiving shoe opening and the foamed ankle collar may extend at least partially around and over a foot receiving shoe opening. The ankle collar is capable of being compressed by the user's heel during foot insertion and the ankle collar may exert pressure on the user's ankle once the foot is inserted. The ankle collar may have a flattened region along its length forming a downward angle from the topmost region toward the front of the article of footwear. The ankle collar may be located along at least a portion of an inner surface of a heel cup and the heel cup may have a shoe-horn like configuration. The ankle collar may reduce the dimensions of the shoe opening when not compressed.

An article of footwear comprises a sole structure and a footwear upper secured to the sole structure and defining an ankle opening. A device comprises a control bar having a center segment secured to a rear portion of the footwear upper rearward of the ankle opening, a medial side arm extending downwardly and forwardly from the center segment at a medial side of the footwear upper and fixed to the sole structure, and a lateral side arm extending downwardly and forwardly from the center segment at a lateral side of the footwear upper and fixed to the sole structure. The control bar depresses downward under an applied force to a loaded position as the side arms resiliently bend, storing potential energy that returns the control bar to an unloaded position upon removal of the applied force, the rear portion of the footwear upper moving with the control bar.

A footwear article includes a collar slide that is conducive to hands-free donning to secure the wearer's foot during wear. A footwear article capable of hands-free donning comprises a sole including a ground-contacting surface and a foot-facing surface and an upper having a heel region. The footwear article also includes a strobel, the strobel affixed to the foot-facing surface of the sole and a collar elevator comprising a heel structure, the collar elevator connected with the strobel and coupled with the upper in the heel region. The collar elevator includes a collar slide forming a ramp interface during a donning operation.
