Been wearing Salomon GTX3's for a couple years and they are quite light. Really started appreciating a lighter boot, but the Salomon's leak pretty easy despite being Gore-Tex and not all that durable. They are nice for kick-around summer and dry land hikers though and they work well for that.

That got me looking for other light boots and I recently picked up some Crispi Lapponias (sp)? Light as heck, around a pound apiece, but still have some rigidity to them. The guys at Black Ovis said the Lapponias should hold out water better and be more durable than the Salomons and the price is virtually the same. Hoping they might be the answer? As soon as the snow leaves some, I'll start wearing them.
