Rusty,
Chris Wallace and I are big fans of Soft Star. He uses the Roos for kick-around shoes, I got a little obsessed and ordered a pair of Roos and and the Run-Amoc Lites with trail soles after he showed me the Roos. Here's the part where you get some big money saving advice:
1) Soft star rocks, but…
2) The Run-AmocLites are not suitable with trail sole period. If you want these for road running, and you're an experienced minimalist shoe user, get the road soles with the Lites..However the perforations made these instant sandpaper on the trail without socks, and impossible to use for long periods even with them. The grit just invades them.
If I had it to do all over again (I'd offer this as advice to Soft Star even), I'd get the regular non-perf'd RunAmocs with the trail soles for trail usage. Leather breathes well enough as it is, I dunno what I was thinking.
The roos don't have enough padding regardless for rocks, unless you're capable of bare-footing the trail already.
That being said, the Roos are the most comfortable things I've ever put on my feet, including all socks/shoes/VFFs/whatever, the trail-soled run amocs are a great compromise, and are perfect for normal trail use, but don't go "Lite".
Traction is not a concern, with the trail soles if you're used to VFFs or anything similar, it's superior. Durability of all styles I've tried is quite good. The leather bottomed Roo's are surprisingly durable, just no padding. I use them rain or shine.
Edit: Forgot to mention also, that the Lites, due to perforations, will stretch out significantly over time, such that they slip-and-slide under normal use, unless using heavy socks. This isn't an issue for fore-foot strike running, but for variable strike hiking, becomes problematic.
