They never responded to my email so I can say that the customer service is horrible. Le scarpe sarebbero anche comode come suola, ma per me erano decisamente troppo strette. I took off a star for the weirdly textured lining, which took getting used to. Way to big for my head if you tighten up the Velcro strips you can no longer hear the music. The Xtreme 2 sounded exceptionally bright, which might be good for casual music listeners who don?t give much attention to music, but for me, it was a deal breaker. They just want your money. I ware cotton Body Armor workout socks and the slippers are slightly lose at the heal so it feels the slipper may come off otherwise they are comfortable. Since the failure occured after 30 days the vendor (Zappos Retail) is not responsible nor do I blame them. The wireless feature brings me so much more freedom in my movements that I didnt have before. I wear them minimum 5 days a week for no less than 8 hours a day.
