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.
