These booties could benefit from a more durable sole. The bottoms wear out too fast.

my favorite!
ive been using these a long time. ive tried countless other brands too. even tho they're only 3 mm, they are very warm, and nearly leak proof! only down side is they wear out quick if you wear them walking in the sand because there is no rubber on the sole. then they get leaky... but the price is right, and they are very comfortable. i can always rely on these to keep me warm up here in washington state!

Pretty good
This is a super basic design. The stitching is nothing to get excited about and they may or may not last long. However, they slid right into my fins and I didn't even think about my feet once in 3 hour 50 degree water session. And really that's what I was looking for.
