I'm taller and heavier, 6ft 1in, about 250lbs. I lift weights 4 times a week. These are just my fucking sneakers. "I went jogging in them the other day and surprisingly they felt great even though they didn't have laces. They were the only thing I had near running shoes. They call them sneakers but I can't see that." they are not for serious runners at all. The upper is too thin and flimsy and the sole is too soft for road running. No tread, it's just "cloud foam" But I can wear them to work or on longer hiking days and they hold up well. If they snap, you're probably making too much or under-ordering, or you forgot to trim your nasty toenails.
