Great trail runner. Its not nearly as beefy as the Raptor and the sole will wear out faster, but this is an awesome shoe. So comfortable. The material drains and drys VERY fast. My favorite all around running and scrambling shoe. I've raced in it, gone down canyons, and slogged up rivers. If I am on my feet all day in nasty rocky terrain I don't feel this gives me quite what I need for underfoot protection, but I'm on my 3rd pair, so clearly it fits most of my needs. Feels light on the feet. There are a lot of good/fun shoes out there. I love the fact that the experience is different for each type of shoe I chose to run in on any day. But on most days I go for the helios! Also, I agree with other reviewers: This shoe runs a bit smaller - about a half size smaller than the Raptor.
