I dont dare reorder a different size because with this company, you have to pay for shipping to and from. My shoe size is 14, and my feet are wide. They have been the best sounding headphones I have bought in a long time. Ich trage gern Sandalen von Rieker oder Remonte. Threaded cable and seems quite durable. The bottoms were dirty and you could tell someone had walked across a nasty floor with something stuck to the bottom. Works for us! Most slip ons I buy in a size 9 but normally wear a 9. Instructions for use are pretty simple You can increase/decrease volume, forward or reverse tracks, and play/pause. They look great with or without socks and are easy for older toddlers to independently put on and take off.
