Im 58 and go to boot camp five days a week with my daughter. This is by far the only shoe that keeps my knees from hurting. They are like walking on a pillow top mattress, but with great stability.  This color is a little bright, BUT for $60 instead of $150 Ill deal with them not matching occasionally. Also, they run a tad short. My regular shoe size is between a 6-6 1/2, so I go up to a 7 in athletic shoes. This size 7 shoe was a little tight with a sock, but loosened up the first time wearing them and are now perfect.
