After receiving our shipment, my wife and I were very pleased with craftsmanship and detail, just awesome. 5 to 11 US. Only reason I saw it was because I looked down as I was getting back in my car. The rest itself is smooth and comfortable. She also wanted this pair because, even though she is older now, she is a smaller person. I was hoping this would be a silver bullet for my foot pain. Before it shorted out it was fine, with good sound quality. Whats the point of buying slippers if they wont stay on your feet? Cannot express how much this product saved me. I could have cut the bezel but decided not to as we do not plan on using the sd card.
