Perfect for Cenotes – Lightweight, Quick-Drying & Comfortable
Size: 6 Women/5 Men, Color: 1a-407 White, Size: 6 Women/5 Men, Color: 1a-407 White
Perfect water shoes! The material is thin, but they dry very fast, which was exactly what I needed. I’m usually a size 6.5 and sized down half a size, and the fit was perfect. I used them for swimming and walking in cenotes in Mexico for about two and a half hours, and they were comfortable the entire time. Great grip and very practical!

Great quality & comfortable all day wear
Size: 13.5 Women/12.5 Men, Color: 1e-414 Gradient Blue 35
I purchased these for my husband to wear on our vacation to Jamaica. I planned a trip to one of the many beautiful falls and water caves" in the area. The travel instructions stated we would be "climbing rocks & walking through fast moving water" and water shoes with good traction were advisable. The excursion was amazing and my husband was very impressed with the quality and durability of these water shoes. They kept his footing steady, kept him from slipping and were extremely comfortable for all-day day wear. We strongly endorse these water shoes for any water sport or easy summer wear.

I would give these 6 stars if I could
Size: 7 Women/6 Men, Color: 1a-407 White, Size: 7 Women/6 Men, Color: 1a-407 White
We're going on a trip soon where we'll be jumping into some natural waterfalls and it is recommended that we wear water shoes. I've had water shoes before and so far not a fan. They're tight and ugly, making my feet look like a squishmallow (like rock climbing shoes).
Searched on Amazon and saw these. Hey! The pics online actually looked pretty neat. They reminded me of those funny shoes with toes. I read the reviews and everyone said they were the most comfortable shoes ever. So, I drank the koolaid and bought a pair for me (white) and a pair for hubby (grey/green). We just tried them on.....
So, I'm normally a size 7 (women's) and my feet are wide. For slippers, I fit into a 6. So I took a chance and ordered size 37 (which is honestly the normal EU size for me, but being that these are made in China, who knows what I'll get). Hubby is normally a size 10 (men's) and his feet are very slightly narrower than normal. So again, we took a chance and ordered him size 42 (besides, the size 9.5 wasn't even available as an option).
Holy mother of metatarsals what sorcery is this? I put these on my feet and they felt like a soft hug! Wow! And they fit! At first I thought...oh no, they're a bit BIG. But I was sitting and so when I stood up, my toes went to the tip of the shoe. Remember how I said my foot is wide? Well oddly enough, I had to pull the straps really tight so that they'd feel more secure. This is the only downside: Because I tightened the straps quite a bit, there's a lot of extra elastic (6-8" lenght) that is going to dangle around the top of my foot (see pic). So a lot of creative tucking it in is necessary. Hubby's shoes fit him perfectly. He didn't have to tighten his as much.
Very impressed by the construction of the soles; they feel sturdy and solid and flexible yet thick enough to prevent sharp rocks from poking through. I also love the shape of the toe box. It's a square shape but flattering (on me as my foot is wide). Plus, because of the mesh fabric, stitching, and detail, the shoes look like stylish athletic shoes and not plain neoprene water shoes like the kids wear. They are also extremely light and have holes in the bottom for drainage. The fabric is super soft and stretchy and they are a snap to put on. Super awesome!
Not gonna lie: I don't even have socks this comfy.
Could I have gone a size down? I probably could but because of my wide feet, that would be too risky. If you are a size 7 naturally with narrow feet, I tend to think yeah...you may want to consider sizing down a half size. But my toes hit the tip of the toe box when standing up and I don't want them to overhang. Any tighter and they may fit but they won't look good imo.
I could see why people want to wear these all the time. They're so comfy, I bet you can even sleep in these.

great water shoe!
Size: 7 Women/6 Men, Color: 3f-410 Rose Red
I absolutely loved these water shoes! They are surprisingly very comfortable and slip resistant. The sole is very thick and the material is pretty quick to dry. I purchased them for my cruise port excursions and wore them dry, in the water, and walked around after being in the water—no blisters or uncomfortable rubbing. I would say they are maybe a little on the larger side for women. I can range anywhere from a 7, 7.5 to an 8. I purchased a size women’s 7/men’s 6 and it was perfect. I am excited to wear these at the beach and in the creek this summer!

Great Find
Size: 8, Color: Blue
Cute, comfortable, colorful have soft straps. I was very surprised by the both the quality and comfort of these Flip Flops. The price is so affordable that I bought several pairs in other colors. They are light weight, have ample arch support, fit true to size and can be worn with jeans, short or a casual dress. They really do look just as good as any of the high-priced brands.
