It’s a pretty pair of shoes, delivery as stated.I’ve only run 50 miles in them so far, they are light on the feet, the Gel action helps absorb the shock of my stepsI use them on a treadmill inside, no problems experienced so farI purchased them as a direct replacement for my old shoes, the new ones are slightly narrower, but still comfortable.Arrived much quicker than initially projected. Very comfy shoes and have helped a lot with painful shins. Have allowed me to run further without exerting too much energy. Highly recommend.Good fit great product delivered on timeI had many asics shoes and all of them in one size but these shoes are smaller.Very old stock and high price but brand quality is just okay, can’t compare this with Reebok or Nike brand shoes. Reebok is way better than Asics as per my experience.
