It actually keeps the water out. Love it.

Fit perfectly, comfortable, warm and waterproof.

From a material and overall quality standpoint, these are good neoprene socks.The issue that I'm encountering is that the sizing is odd. Large is equivalent to an 8 - 8.5, while the XL is equivalent to 9.5 to 10. Unfortunately, I'm a 9 so I ordered the XL, thinking it would be best to size up, but the XL is too large.Additionally, the size chart in the product listing is EXTREMELY difficult to read. If the seller is reading this, please make it easier to see the size chart by removing the background photo from it.Bottom line: aside from the size issue, these are pretty good quality neoprene socks. They do a good job of protecting your feet from hot sand, and the rubbing of your fin straps which may cause blisters.
