They are very comfortable and supportive but not durable. I rode them about 600 miles in 6 months - walking and jogging on a 50/50 mix of tarmac and trail. The upper held up, but the outsole lugs were completely worn from the center to the outside of the forefoot and back of the heel. My previous Asics lasted about 5 times longer. That being said, these Sauconys are now selling for about half what I paid for, so I'm considering getting another pair.
