Running in these shoes for the first time this morning - they are roomy in the forefoot and toe and are lighter than the Altras I usually run in. If you like a less structured and form-fitting shoe, this shoe might be for you. The profile is good for gravel and trail and grips well. Underfoot technical terrain like rocks and roots feels better than the thicker, more durable Vibram outsole, but I think I'll like this shoe best on less technical, smoother trails. The BOA system works well - if I had one small complaint, I would wish the BOA was a bit tighter as I have a very narrow foot. Unlike other reviewers, I had no problem getting my foot in the boot - it felt roomy to me. I'm happy to add them to the rotation!
