I have been looking for various styles of Merrell's Q-form support system. This shoe fit the bill. Comfortable and stylish. I wear the Q-form shoes almost exclusively because of my "old timers" knees. Prior to discovering Q-form, my knees were creaking most days. Since I've been wearing Q-form shoes (a couple of years now), my knees have been much less bothersome. Keep them coming, Merrell!
