Most comfortable pair of running shoes Ive ever owned!!  Jog on the treadmill in these daily for 40-75 minutes and Im getting another pair now for when these wear out. Super cute too!!  Fit perfectly!!  Broad toe-box are perfect for my regular width feet (I need a roomy toebox for pain in my big toes and these fit the bill).  I have high arches & don't need to use inserts with these...so Id have to say this should would be wonderful for anyone who needs excellent arch support!!  I wear an 8.5 in regular shoes but most sneakers run 1/2 size small and these sneakers are no different. If you don't know your sneaker size or Nike size, order a 1/2 size up. These sneaks are the most lightweight Ive ever owned and its an awesome feeling when jogging!!  Not too heavy on the ankles and mesh keep my normally super hot feet relatively cool!!  Im super impressed with these running shoes!!!  No breaking needed in my case.
