runs big am a size 9 in women but 8 fits perfect size downI always struggle with water shoes and insoles moving and make walking uncomfortable. This pair doesnt do that. I went down half size to get snug fit and it was perfectThey are very cute and comfortable. Did I mention, cute!!! They are light weight and give you the look of a tennis. They run true to size.Best water shoes ever! Very comfortable and well designed. Look great and feel great while walking on very hot dock. Performed perfectly during cliff jumping and swimming in the lake. Perfect for just boating around the lake as well. Stylish enough to be worn into lakeside restaurants.I wore the shoes one time and my toe nail created a small hole in the top of the shoe. Haven’t had any other issues since then. Still wear them and I get compliments everytime I put them on.I like the style and that they are all black. I did purchase my regular shoe size. I have fat feet and tend to get swollen from standing all day long. Since my feet are fat they were a tight fit and would hurt my feet.They are super comfy and the color is beautiful! I really like them!This is my second pair of Leyang water shoes. The first seller is unavailable and I had to search a long time to find a replacement. I had ordered two different water shoes to replace my well worn ones from a few years ago and even though those were the same size (37), they were both way too big by up to 1.5 inches and very loose.Returned them and by luck found the same pair.Fits snugly and securely with ability to tighten if necessary.They also have a little rubber reinforcement on the toe. It does wear through but is more sturdy than just the mesh on most of the other shoes.I used these for weeks at a time and now won’t even wear flip flops because of the pain flip flops cause in my legs and the way they change my walking gait.These aqua shoes fit with enough flexibility I never have gotten blisters or slipped.The downside is they tend to REALLY make my feet stink…horribly. This was only after many weeks of daily wear however.I washed them in the shower with soap and then slathered hand sanitizer inside and let them sit with that for an hour then rinsed and let them dry in the sun.No more odor in shoes or feet.Soap and or baby powder doesn’t work, it has to be be hand sanitizer.I am ordering a few more pair to have because they are my go to shoes for warm weather and they don’t take a lot of space when traveling. Highly recommend.I usually wear a size 6.5 in regular shoes and 7 to 7.5 in boots.
