[57] ABSTRACT
An athletic shoe having an upper portion (15) fixed to a lower portion (16) comprising a midsole (21) and an attached wear surface (22). To provide both cushioning and stability to the foot the midsole includes slots or channels (25, 27) extending at an angle other than normal to the wear surface so as to provide a cushioning effect when forces are exerted through the shoe in one direction, as during the heel contact phase of running, and forming therebetween crossbeams 23 to provide stability and force transfer from the foot to the ground as required during the push-off phase of running.
