I have run about 180 miles in my pair in about 3 weeks and have a few detractors to list. First, the sole is coming unglued from the foam. Second, the lugs seem to not be very sturdy as I am missing parts of a few and most show more wear than I feel like they should at less than 200 miles. Third, the mountain laminated picture on the outside of the shoe is peeling off. Fourth, this shoe is sized larger than previous models, so you would need to size a half size down. Fifth, because it is wide, turning sharp corners at speed causes my foot to tip off of the edge of the shoe because there isn't much lateral stiffness in the upper.<br /><br />Now some good: Much lighter and faster feeling then the previous models. Cushioning is very good and smooths out rocky trails very well. Traction is great (until the lugs come off). Overall the fit is nice and having a soft upper really lets my foot expand as needed. No blisters or hot spots with these shoes.<br /><br />Final thoughts: Again, durability and sizing seem to elude Altra. If it wasn't for the wide toe box and solid trail features, I would look at different brands. Their customer service is poor, and there isn't any help with the &#34;warranty&#34; unless you purchase shoes from them directly, which in most cases cost you an extra 20% over what you would pay elsewhere. It would be nice to see them stand up for their product and make it right by an unsatisfied customer.
