I currently use the Hellbender stockingfoot breathables.
I had them for about a year. They started leaking a while back, but nothing Aquaseal couldn't fix. Recently(past month or so) they started leaking again. This time I can't find where the leaks could be.........I honestly think they're just losing their waterproofness from the knee down.
Keep in mind I'm very tough on waders, but then again I also wet wade most of the summer......
If you don't fish all that much, don't bust through a lot of brush, and don't walk for miles then I guess they're a good buy for the money.
