Ordered these for my husband who is having knee surgery. I wanted to sell slippers with a strong non-slip surface. Slippers LB Evans Darren are suitable for this. The slipper is very well made. The materials used in the construction are of good quality, there are no rough edges for heel or toes to rub. Slipper is attractive. If it had to be worn outdoors, the durable outsole made it able to do so. I originally ordered them in a size 10 but had to return them as they were too small. So my guess is that they run a little small and the customer might want to order a size up, especially if the customer is wearing socks. The return process was easy and quick. Then I ordered size 11 and they fit perfectly. I chose 4 stars due to sizing issues. The quality is definitely good.
