My feet have changed a lot in the last several years of road running, trail running, and backpacking. I went from boots to New Balance 907's with Superfeet inserts, then the 907's with stock insoles. Now I've finally found that my feet accept and expect a lot of flexibility for off-road activities, and the Inov8 Flyroc 310's fit the bill perfectly, even though I run in motion-control trainers on the road.
I'm just hitting about 150 miles on my first pair, and the rubber lugs are starting to wear down, and the midsoles have just started to compress. These are visual differences; there is no performance change in the shoe (yet). I have also replaced the insoles with something a bit more padded, simply due to wear. Perhaps a new rubber formulation might instill more confidence that I might reach 300 miles before needing to retire this pair, but it's just like tires: you get sticky or you get durable. Moment to moment on the trail, I'll take sticky.
All the other reviews hit the highlights - light, fast-drying, comfortable, breathable, flexible, great traction - but they've freed me from bringing camp shoes (no need, these are so comfy) and their lightweight construction totally belies their bombproof durability.
The feel of the ground through these shoes changes how one hikes. I've gotten much more aware of where I'm stepping, and I think that might have as big an impact on my foot comfort as the shoes. No more blindly stomping forward on sharp rocks just because my boot let me. Walking and running becomes more active and less passive, and my feet (so far) are telling me that's a Good Thing.
The only time I don't wear these on the trail is when I'm mountain biking. Otherwise when I'm off the roads and active, it's Inov8 Flyrocs or nothing. I just ordered two more pairs.
