Disposed over the outsole is a mid-sole pad with clip openings configured to be aligned and registered over the clips located on the outsole. Disposed over the outsole is a shoe upper with a plurality of hook members configured to attached to the clips located on the outsole. Disposed inside the shoe upper is air upper sole pad that covers the mid-sole pad.

Customers can purchase different shoe uppers and exchange them on the outsoles to create different styles of footwear.
