I LOVE these sandals! Theyve completely replaced all my other black sandals and I wear them nearly every day. I usually wear size 8.5 or 9. I went with size 9 and they felt just a tad small at first, but quickly stretched and now they're extremely comfortable. Occasionally I have to tug at the zipper more than I feel like I should have to, but thats just a tiny problem and its only ever taken a few extra seconds and a little extra effort to get them zipped up. Ill definitely be reordering these when mine get worn out!
