He loved these shoes. Even though from man made material, they look like leather and don?t feel cheap by any means. So I thought I?d gamble on this one. Not the most comfortable feel, but doesnt slip, making it ideal for using at the gym. Excellent , love this sandals on doit faire sur mesure fit is as expected, wear 11 tennis shoe and 11 teva pivot fit right on. I placed one unit between couch cushions (not under, just between), went into the kitchen and pressed the button. Lovely, with a hint of edginess that was exactly what I wanted. I received it quickly, but it doesn?t work.
