well i have been geeking out on this topic this summer, trying to get a good setup so here's my $0.10. knowing that I also gave up on chacos several years ago, my choices are for kayaking but i can use em anytime i actually work a trip. and toe protection is underrated on the river. GLW finding sandals...keen seems the obvious choice to me, although some are a bit dorky. i am not sold on sandals in general anymore. flipflops immediately post trip tho
# 1 choice....Astral Brewers look like the shizzznit.these are definitely my next pair of river shoes.supposedly for around town too,all chingon with 5.10 sticky rubber soles. they sound like the shoes you are looking for. I guess its all conjecture so far, cause idk how they'll fit in my playboat. but cant wait to get em.they're on order.
Astral Men's Brewer Watershoe at NRSweb.com
(#2)5.10 water tennies are the confirmed business. but way pricey.... :/
Water Tennie - Five Ten
(#3)keen gorge booties are really good for cold weather; i has some.
(#4) NRS attack shoes...are pretty alright, or were 4-5 years ago....
what i wore all summer= Vibram five fingers.... not perfect but they got me through the summer, as long as the waters warmish. theyre like the grateful dead. either love em or hate em... they are truly awesome for creaky ol tele/snowboarding knees when running tho....
and not compatible with drysuits. lol.
ALSO.heres some nitty gritty for you... go to keen.com....look for the PRO link, apply and tell them why you are a "qualified member of the outdoor community" and they offer 50% off $600.00 worth of retail prices...on everything....! m/w/kids/flip flops/ winter boots etc.... super cool pro form.... very kind of them... Gorge booties are $45.00...!
and then there's NRS. if you're a raft guide you otter know about that one ;]
hope this will be helpful to you... all links straight from my firefox history....
