SkinShoe - Change Skins, Not Shoes

The SkinShoe consists of two parts: 1) the bone, an inner shoe/sole, 2) a skin. If you want to switch shoes you simply slip the bone into a new skin. Prices are still pretty high at the moment (50 dollar for a bone and 125-300 dollar for a skin) but lower the price and add 'design-your-own-skin' features and who knows how popular these shoes are going to be.
