>>1195155Eh, Idk maybe just for a city park and well paved trails with almost no incline? I've done those in desert boots with crepe soles. Then anti-tracking military units also use soles with zero tread and seem to find ways around that fact.
>>1195213I've got a pair. The tread lasts a while and is good for mud and soil, but it picks up pebbles and is super slippery on wet rock, and wet smooth floors. I only ever took them on trails, never anything rougher than that. I'd also advise against carrying anything too heavy as they don't really have any ankle support but are very light. They have basically zero padding, so long trips might end up being very painful.
