Barefoot Exercise
Americans are raised on the athletic shoe as a basic supply without which one cannot engage in physical activity. Arch support, ankle support, and shock absorption are all considered to be necessary, and exercising without them is thought to be dangerous. But of course our bodies have evolved to function without external reinforcement, and our feet are designed to bear our weight all by themselves. Walking and even running barefoot trains all of the little muscles in the foot and ankle region, strengthening them and reducing our dependence on external help. Barefoot exercise also allows a greater range of motion to the foot, which can increase flexibility of that region if performed properly. Especially if you have exercise mats available to reduce the hard impact of a wood or concrete floor, try exercising barefoot for a couple weeks and see how it strengthens you from the knees down!
