There has been a lot of talk lately on proper footwear for kettlebells. Contrary to what you might think, the best footwear for kettlebells, and free weights, is BAREFOOT, or shoes without a soft heel (Vibram Five Fingers, Converse Chuck Taylors, Addidas Racing Shoes etc.) Current research is showing that a cushy heel (running shoes) are not actually beneficial for your feet.
When lifting weights, the flatter/firmer your shoe soles are, the better. At home, barefoot is best. Also, it's best not to lift on soft mats. This can cause you to loose your balance, and hurt yourself; I know, it's happened to me in the past! Barefoot, on a firm surface is best.
As Pavel says..."happy feet are fast feet"!
