These interchangeable shoes by Marshmallow Skins are kind of like a cross between those convertible pants that zipper off to shorts and those watches with interchageable faces. If you're tired of wearing orange sneakers, don't despair...zip 'em off and zip on the purple! Each set comes with 4 colors but you can buy other shoe tops separately. According to the website, the target market was originally for girls between the ages of 4-11, but adult women liked them so much they expanded their offerings to include adult sizes. Marshmallow Skins is designing a purse (who says purse anymore?) with the same concept - "zip on new colors to match the shoes" (matching colors? yuck!). It's a pretty cool concept, but the shoe could really use some help in the style department.
