Abstract: A reconfigurable article of footwear has a reconfigurable insole inserted through an opening for receiving the foot of the user that is supported on a midsole. The reconfigurable insole has a primary footbed and a removable footbed. The primary footbed has a top side for supporting the foot of the user and a bottom side for contacting at least a portion of the midsole and for engaging the removable footbed. The removable footbed has a top side for engaging a portion of the bottom side of the primary footbed and a bottom side for contacting the midsole. Detachable corresponding and aligned fasteners on each of the bottom side of the primary footbed and the top side of the removable footbed detachably secure the removable footbed to the primary footbed.

Abstract: An outsole having a plurality of traction elements extending transversely across its lower surface and a plurality of support walls extending transversely across its upper surface.
