Six months ago I would not have believed that I would be saying this. I got a pair of insulated bootfoot Hodgman Wadelite breathables to try out and have fallen in love with them. I used to swear that the only way to stay warm steelheading was with 5-mil neoprenes with an insulated bootfoot. I'll stick with the bootfoot part; there's no way to keep your tootsies warm in stocking foots, but I put in a few days last month in 35-degree water and, with a pair of thermal tights and polarfleece pants underneath, was warm and comfortable all day long and even while breaking ice through a backwater to get to the river. I tried my old 5-mil neoprenes the other day while beach fishing and quickly found myself looking forward to getting back to the car to get out of the damned things. How durable are they? I can't say yet, but so far I've experienced no leaks of any sort, even after whacking myself with a misdirected spey cast that I was sure had punched a hole in them.
