I normally wear an eight but since they were only available in half sizes I went with 8 1/2 and they fit great. As others have mentioned, these are perfectly flat soles; there is no arch. I gave them one star for support but didn't deduct anything from my overall score as I knew what I was getting. There are three silver versions and I purchased the simpler one which looks clear in the photos but in reality is an iridescent pale purple. Either they sent me the wrong color or that's just how the silver presents. The color actually works out really well for the costume I'm wearing so I'm keeping. But also as other reviewers mentioned, OMG to the WEED smell! The room in which I opened the package reeks of weed! As soon as it stops raining I'm going to leave them outside for a few days and see if that helps. Lost a star for the smell alone.I love these shoes. They fit well and are comfortable. I bought two pair. The only thing is, when I opened the package. Actually before I even opened the package they smelled like pure weed. I tried to wash them to get the smell out with no avail. I wore them at home and my sister came over and asked me if I was smoking weed… after some time and a few washes later the smell came out. But it was a few weeks later.I'm usually an 8 or 9 depending on the shoe, I got an 8.5, I thought they looked too big at first, but they fit beautifully. There are one or two spots that rub, but I go through the same thing w my flip flops every year. Just wear them around the house til they break in and your feet get used to them. I did use my nail kit to clip and smooth any rough edges. You only need a light touch in some places. I will say, I expected them to be lighter or clearer in color, they don't match the picture, or anything I planned to wear them with, I almost returned them, but I slept on it and decided I like the dusty rose/rose gold shade. I really like these cute little summer flats, just know the pink isn't true to the picture. (Really loved the white-ish/silvery/clear ones, they give off a Cinderella vibe.)I have these in clear and black. I prefer the rounder shape of these versus the jellies I wore as a kid!What a great pair of jellies! They are comfortable, fit true to size and match everything! They did have a smell at first, but no biggie, I just left them outside for a couple of days and it went away. Definitely worth the purchase!Todo me gustocomfy enough, too.These aren't walking shoes! But they are super cute and perfect for what I need them for. When I'm making a quick trip to the store or want to change out of my heels, these shoes have been great! They fit nicely in my purse and don't "ruin" my business ensembles. I'll definitely buy again!
