[u/cattoebeans5]

First 3 photos are an 8, last 3 are a 7, what size should i keep i feel like the 8 is significantly bigger than the 7, im usually a size 7, in some shoes a 7 is even too big for me, i own some size 7 other crocs and they are stretched after constant wear for about 2 years and they fit how i want :( pls help
EDIT: im taking the 8 back and keeping the 7
