@xahteiwi I have no experience with long runs but have you maybe looked at https://www.leguano.eu barefoot shoes as an alternative (like the Spinwyn model)? They aren't toe shoes but also non-cushioned and lightweight. The company claims that the sole is very robust and durable. I own both Vibram KSO Evo and Leguano Active and so far the latter survived longer.

@kaspi Hmmm interesting! No, I hadn't heard of those before. I wouldn't mind that they don't have toes; I do occasionally run in Skinners too. I'll see if I'll give them a try — thank you!
