Abstract: A removably insertable footbed assembly for adjusting sizing of an article of footwear is provided, wherein the footbed assembly adjusts the volume available within the cavity of the article of footwear. The footbed assembly comprises: a) an upper component having a heel region, a midfoot region, and a forefoot region, and having an upper and lower surface, wherein the lower surface of the forefoot region, the midfoot region, or both have at least one attachment element for releasably attaching a lower component; and b) a lower component having a midfoot region and a forefoot region, and having an upper and lower surface, wherein the upper surface of the midfoot region, the forefoot region, or both have at least one attachment element such that the lower component is releasably attachable to the upper component.

Abstract: The present invention is related to an article of footwear that has an upper extending around at least a portion of a foot. The outsole is secured to the upper. The article of footwear has a midsole that is detachably secured to the outsole. This midsole has a vertically projecting generally dome shaped support element located in the heel portion of the midsole. The dome shaped support element may be in contact with outsole interior sidewalls only while in an compressed state or it may remain in contact with the interior sidewalls in an uncompressed state. The dome shaped support element is at least partially covered by a cushioning cover that is made of a material less stiff than the material comprising the dome shaped support element. The cushioning cover may be partially covered by a heel plate that extends from the heel of the shoe towards the toe of the shoe. The heel plate may or may not extend the entire length of the shoe.
