I bought 2 of these and then returned one! They don't fit the size. You are larger than the requested size. They don't have much support either - but they're not your typical slippers (although they're decent in that too). They are very breathable, flexible, washable and very comfortable. I kept one because I needed it. I sent the others back because they are larger than my recommended foot size. They have a "strap" that makes them look like sandals and keeps the foot inside. You can just leave the strap in front and use them like crocodiles. They're ribbed and grooved to keep your foot in place and won't slip on wet floors.
