Bought this shoe in May 2020. They are only used inside, on a treadmill. They are not used for anything but treadmill workouts. I have logged approximately 200 miles on them to this point. It is a light, well fitting and supporting running shoe.However, the sidewalls are splitting, the treads are peeling away from the soles, the rubber is flaking. Just poor quality. I had a pair or Saucony before this and I probably will go back due to quality concerns. I reached out to Asics North America who responded quickly, asking for a battery of information (pictures, receipts, etc). But, then they never responded again despite me reaching out multiple times. Why should I stand by a product that the manufacturer won't stand by?I've been buy Asics since I had foot surgery...The Cumulus 17's were the most comfortable and after that they started to get worse but still better than any of the other brands seeing that Asics still makes shoes for walking/running Pronation... I bought the 22's.. They're everything the 17's were but lighter.... So I bought another pair after wearing them less than a day! Will probably buy a few more just to have when these wear out! Do i recommend Asic's Cumulus 22's...Yes But they do run about a 1/2 size to big!
