Purchased a pair of ATR 5 Challenger trail shoes two years ago. I have run on average less than 2.5 km per week. After 2 years the shoe mesh has split in multiple places especially around the toes. I have never had a pair of running shoes in my life that have failed so badly and so quickly. I expect to be able to keep using shoes that have lost their spring as secondary shoes when I buy new ones. I contacted Hoka One One and it was a polite "tough luck" we provide a one year warranty. I can only assume from their response that they consider such failure normal for their shoes and so recommend buying a different brand if you want a more robust shoe that lasts. A pity as they are super comfortable and otherwise a great shoe
