Don't buy anything without felt studs in my opinion. I live in Colorado and got tired of slipping and going down on one knee in freezing water. we have some slick rocky rivers. The studs cured that. The only thing negative is wearing them in a driftboat can scratch things up a bit.

Also make sure they're not too tight. I made that mistake on my first set. We fish in the winter here and I tried to wear extra thick socks and my toes were colder yet because my boots were too tight. I always get a size bigger so I can wear poly socks over wool.

Good luck!
