Nice

"Nice"

Gabriel L. (5/5)

Perfect fit

"I use these for windsurfing here in Florida when in spots that might have less than a nice sandy bottom, so more for protection than keeping my feet warm. I like how easily they go on compared to an old pair I had. I wear a 9.5 to a size 10 shoe depending on the type and I ordered these in a 10 and they fit perfectly so I would suggest that you buy just one half size larger than your regular shoe size."

Bill H. (5/5)

perfect

"nice grip and perfect fit"

Martin S. (5/5)

Awesome warmth!

"Awesome warmth!"

Maria G. (5/5)

Good and warm

"The booties run a little small in size, I went a size smaller. Very warm and comfy but snug. Love them"

Sonny V. (4/5)

Good fit, not bad to

"Good fit, not bad to get on and off. I’m an 8.5,so got an 8. They’re a bit tight, but I would rather have that than too loose."

Daniel C. (5/5)

Extremely comfortable-But look kind of

"Extremely comfortable-But look kind of flimsy I hope they hold together-I have an old pair about 25 years and still work let’s hope there the same."
