This is a smart idea that Treehugger spotted: a shoe system that offers an inner-shoe that lasts forever and replaceable ‘skins’ to keep your feet looking fresh. TH says:
Mark Klein… came up with an interesting idea: separate a well fitted, orthopaedic core (the bone) from the stylish “skin” that can be changed in seconds. Result: Instant customization, comfort and style, without the waste of shoe structure that sits in the closet. The bones can last almost forever, while the skins can be replaced as they wear out.
…New York designer Dror Benshetrit… set out to create a simple yet iconic shape that he believed could stand the test of time.
