I have flat feet and bunions, second toe presses down more than big one. These shoes have a rigid sole and keep all balls in the right position. Great for my training legs. No more other brands, finally found the perfect shoe that helps. I rode uphill and downhill for over 50 miles in the hot desert. 2-4 miles every other day for 2 months. Thanks to Under Armor for thinking about my legs. I can walk 2km without pain again.
