Hi guys, I have been wearing the Simms Rivershed Vibram sole boots for over a year now. I really like them. They aren't quite as good in the water, especially the Kern as felt, but are pretty close. I take it a little slower and tend to use my wading staff more(as I should always be) I've taken a couple falls, but not as many as I have taken with felt boots. While they are slightly more slippery in the water, out of the water is where these boots shine. They really stick to the rocks on the shore. Most of my worst falls were not in the water, but moving along the bank. Wet felt is really slick on water polished rocks, even on granite rocks. The Vibram really makes it safer on shore.
As far as cleaning, no one ever said these boots don't need to be cleaned. I usually just put them in the freezer for a couple days. If I've been in real muck and am worried I got into a mess of snails, I'll soak them in bleach before I freeze them.
As with anything there are good points and bad points. These boots stay much lighter when wet, much easier to go all day in. They aren't quite as good on really slick rocks, but I quickly adjusted to how they work wet and I can't really tell much difference. They are much better along the bank and I think they overall are better boots. Even if they aren't better, the difference, to me, is worth the effort to help prevent spread of invasives. I usually don't wade in(sorry)
on things like this, but as I read, I felt(oops) like no one really knew where the rubber met the road, or streambed as it were.
Later, Raider
