I wear a 7.5 and that is what I bought, they do fit true to size but the ankle straps are a bit loose and no more holes to

I had my husband punch new holes in the ankle strap, now they don’t slip around so much

It was an easy fix, by punching an extra hole on the strap so that i could make it tighter

I have smaller ankles and I put the ankle straps on the 2nd to last loosest hole
