I first ordered a 8 for my daughter because she wears a size 8 shoe in everything including some Mary Jane carter shoes she has. However when they arrived it was a full 3/4 of an inch too long and even all the way tighten there was no making them work. I exchanged them for a 7 and the 7 is perfect length wise however. The sandals are built for those with chubby feet. My daughter doesnt have slender feet but neither are they chubby. You can adjust them to make the sandals fit however there then is this long Velcro sticking out in the back. I may end up trimming it. Otherwise I am very happy with these sandals. They look cute and give her support and comfort for walking
