Abstract
A removable footbed is provided which circulates air and provides shock absorption. The footbed is constructed from a layer of moldable material molded with a concave bump in the heel area and a number of concave, intersecting channels in the remainder of the footbed. Both the concave bump and the channels have perforations which extend completely through the footbed and allow for the circulation of air in a shoe. The layer of moldable material is topped with a layer of anti-microbial foam for cushioning and bacteria prevention and which in turn is topped with a sock-contacting layer. The ventilation holes perforate the anti-microbial foam layer and the sock-contacting layer. A disc or cylindrically shaped open-celled foam sits within the concave bump to bias the bump in an upright position and a layer of shock absorbing material extends underneath the bump and the open-celled foam. The layer of moldable material may end at a step corresponding to the ball of a wearer's foot so as to increase forefoot flexibility.
