These slippers are amazing. They are a tad small only because the only size left I could get was a Large even though my feet are 25cm the slippers still fit well enough as they are super stretchy like a sock. They grip the floor so well for sumo and without the raised heel pad your as close to the floor as possible in comp. absolutely love them. If I could have sized up I would have so if your a womens US8 I would recommend the XL but if you don’t mind a tighter fit they are fine.
