I ordered the PINK MARBLE MOSAIC in sz 5.5-6.5. I usually wear an 8 so with water shoes I have to go smaller a couple of sizes. They were too small. I could wear them but it pinched the toes so I gave them to someone who wears a 7 or 7.5 and she was fine with the size 5.5-6.5. if I had ordered 7.5-8.5 they may have been too large. Pretty shoes.I bought this item to wear during my water aerobics classes. I normally wear a size 7 to 71/2 shoe so I ordered the 7.5-8.5 water shoe. It is a perfect fit, comfortable to wear, good quality, and I have to mention how cute they are.Had them for a few months and regular washings every week after swimming. No hole, tears, or frayed edges. Thin and lightweight but still very durable. Will definitely buy again when needed.I got these to take my daughter to various water parks and pools. They work great and kept the hot sidewalks from burning my feet and had a good grip.These were perfect. They are super light weight and comfortable yet super cute. They dry fast and it’s easy to clean after use.These work very well for the pool and the beach. Worth the price and have a modern look to them.shoes are comfortable, wore all day at a water park, no issues with sliding off, no blisters .I was really excited to get these. These shoes run very small. I had to return and order something else. I also felt the shoes were not same size because the one on my smaller (and we all pretty much have a foot that is slightly smaller than the other) foot was tighter than the one on my larger foot. Foot length difference may only be 1/8 inch, but the right seemed much smaller than the left.Me gusto el diseño y me quedaron muy bien.
