I wore these kicks for a few days, super comfortable and reasonably light for what they are. 1 crossfit session, they were ok, they have some heel rise. They have pretty deep lugs and was concerned it would be too much for crossfit. I bought them for trails and tried em out today. Really impressed, steep inclines, loose steep descents, running on rocks and roots, pretty gnarly stuff, bouncing and launching off volcanic formations, stairs, stairs and more stairs and 2 creek crossings (wet rocks) never lost traction, very stable. Plenty of room in toe box for toes to do what they need, Soles have good protection yet still deliver ground feel. We'll have to see how they hold up.
