I'm a stream ecologist, and wear Simms stockingfoot waders for my field work. There's a lot of hiking up and down streams, and bushwhacking, and the wading boots I wear over the waders just kill my feet. Frankly, they're dangerous - they're so stiff that I can't tell what I'm stepping on and I've had some close calls.
I'd love to have something lighter and more flexible. Any suggestions? They need to keep dirt out; I don't want bits of grit getting in and chewing holes in my expensive waders! At the same time, water needs to be able to drain out of them. Also they need laces to hook gaiters onto; more keeping gravel out.
I considered neoprene kayaking booties, but the wader feet are neoprene - I don't really fancy hiking with two layers of neoprene over my feet! They're warm enough as it is. The gaiters are neoprene as well. Fantastic for cold-season work (which I do quite a bit of) but not so great for hiking into a site on a hot day.
To sum up my requirements: Light -- Flexible -- Dirt-proof (preferably over-ankle) -- Laces for gaiter attachment -- Will fit over neoprene stockingfoot wader
Thanks for any and all suggestions!
