I loved how they bounced when I tried them on in the store. They are a little tight but I figured I could get over that. My feet are quite narrow and I have high arches, so I have special insoles to support the arch. After running 3 miles my legs are very sore and my toes are tingling on one foot. Also, my feet got very hot while running. Nothing like this has ever happened to my Brooks, so I think I'll go back to them.
