I received someone else’s returned product
Size: 7-8 Women/6-7 Men, Color: Sunset
The inner product packaging was already cut open and not sealed, and there was debris inside the socks: clear indicators that the pair I received was someone else’s return. They also run big and are very wide in the toe area. My daughter’s pair also ran big, but at least hers were sealed. Overall quality is a bit flimsy, so we’ll see how long they last.

Decent water shoe
Size: 10-11 Women/9-10 Men, Color: N-laser Stripe
I have to admit, I was a bit skeptical about the quality of and comfort of these shoes because of the cheap price. However, I really do like them. They stay on my feet, are comfortably and non-binding, which is saying something because my feet have been pounded over the years. They even did well when I had to cross some rocks, trekking back to the kayak. Definitely a gods water shoe for a good price.

Perfect!!!
Size: 7-8 Women/6-7 Men, Color: Black-w001
I absolutely love these water shoes. I wear them around the house, getting out of shower, even outside. I’m a stroke survivor that was paralyzed. One of the biggest hurdles of walking again is feeling the ground . One day I thought water shoes would work. After trying a few types I fell in love with these. So easy to put on. Comfortable. Feels one nothing on . I’m buying in multiple colors . Love love love these. Game changer for someone learning to walk again. My feet don’t sweat in them . I wear with and without socks . Easy to wash quick to wrong put and dry. Non slip.

Good starter
Style: KIT
The chemicals are 5 stars, because the Chemical Guys make great and effective products. And they always smell good, but the taste doesn’t match the smell. I wish it came with other chemicals in the kit. But honestly go buy them one by one and get what you need.
