Great Value, heat or no heat at a flip of a switch. Fits perfectly, I?m a 7 got a 7 and I love the holes at the bottom to drain instead of that squishy wet feel these drain right away. Its perfect for that use or for hanging towels in your camper. I?ll add a thin aftermarket insole of some kind just for a bit of cushion. After it was paired, it worked as it should. I honestly just tried it and it?s and interesting scent. It feels really strong and has really good space storage l. Thus there is a slight W shape to the freq response, raised at the ends and the centre - and with corresponding dips between (but don?t let this worry you, it?s fairly healthy, far better than a V shape). I tried these for a couple of days before I did this review. However, I ordered a size larger than I normally wear based on others reviews and the description.
