Comfortable but not nearly as durable as they should be. I've been using ASICS for over 10 years now and have always been satisfied up to now. This shoe replaced my last pair of the venerable 2170s. What a mistake. At first I was very pleased with the shoe. They fit well , felt very good and worked well. But, the soles don't last worth a damn. After 240 miles ( roughly 3 months) of use, not even running use, just fast walking, the soles under the ball of the foot are completely worn out. The heel is holding up OK but the rest is useless. I'm not light weighing in at 200lbs but the last pair of 2170s held up to almost 8 months of solid walking before the cushioning broke down. The soles did not wear out.
