I bought these for my daughter who ordinarily wears a size 8 (women's) to ride Peloton. These fit her just fine in every way except the top buckle strap could not get even close to snug around the top of her foot, her foot would just slip out, so we had to return them. She's never had this problem with any other kind of shoe. The strap should have additional grooves on it so that it can be made tighter. Otherwise these were pretty nice for the price, so it's a shame.
