text: I bought these cuz I tried someone else's on and they we're comfy . One of mine seems shorter than the other , I know one foot may be a bit bigger , but because of the ridge they're not really that comfy . Also they were snug at my instep and I don't think they'll stretch .Im a 7 and wished id ordered 7.5 or 8.  I'll keep them just cuz it's a pain to return them
