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?
