ABSTRACT:
An article of footwear has an outsole with a cavity in the heel region in which a cushioning insert is installed to cushion impacts and provide added lift to the wearer. The heel region of the outsole projects outwardly beyond the periphery of the heel region of the shoe upper to form a projecting peripheral rim. The cavity has an upper wall and a lower wall and a plurality of springs extend between the upper and lower walls at spaced intervals around the peripheral rim. Opposing magnets are mounted in the upper and lower walls in a central region of the cavity with their like poles facing one another to provide a magnetic biassing force which augments the spring load.
