Why Barefoot Shoes?
A conventional shoe lifts the heel, pinches the toes, and hides the ground. Xero ShoesN does the opposite: let the foot splay, keep the heel and forefoot level, and keep the sole thin enough to feel texture.
That is not a dare to go unshod on asphalt. It is a way to keep the muscles you already have working while you walk, ruck, or train.
