are those deadlifting shoes? I notice i have been seeing more and more of them in the gym
Those are Nike Olympic lifting shoes from the early - mid 80's. They're sometimes called the Feuerbach model from old timers because Olympic shot putter, and well regarded Olympic lifter Al Feuerbach helped design them - http://en.wikipedia.org/wiki/Al_Feuerbach .I don't think Arnold ever had a shoe, but he did favor Nike Cortezes in photos, and he did some print work for Reebok too -.
