text: Rider brands are really small sized, I know because I purchased a pair of Rider slippers sometime ago, and they were really small I had to give them away. As suggested by others, make sure to order at least 2 size up from your usual shoe size. I usually get a size 9, but had to get a size 11. Size 12 would have been more comfortable but they no longer have it.<br /><br />That said, these are really very comfortable slippers. The upper structure is flexible but gives you enough support. Highly recommended, just don't forget to order 2 sizes up.
