For a flop is also the original is a real highlight. Even after repeated wear in the sauna it still looks very good. BUT: The black material is made of durable plastic. Who has not very slender feet will get bruises quickly during extended wear and want it off your shoes again. Although I have relatively narrow feet, cut the belt a midfoot. Good: The gray footbed is soft configured. Unfortunately, this does not apply to the edge. Overall quite portable and purchasable. For a short jump into the shower super gym, for daily long run rather unsuitable by saunas.
