Footwear article with collar elevator

Abstract:

A footwear article includes a collar elevator that returns an ankle collar from a lowered state that is conducive to donning up to a raised state that secures the wearer's foot during wear. The collar elevator includes a lever arm. The lever arm may be deformable and biased towards the raised state. The lever arm may be articulated with a biasing force urging the lever arm to the raised state. The lever arm may have a variety of cross sections as well. The lever arm extends from a base, which may a sole portion of the footwear article. The lever arm and the base may be monolithic, permanently joined, removably joined, or otherwise connected.
