I have the Runamoc Dash and Original for work. I understand that some people run in them and some have expressed concerns that they wear out. The leather is thin and comfortable, and I could see how it can wear out.
I run barefoot, and rarely in DIY huaraches. Given the cost of Runamocs compared to huaraches, I will continue to run occasionally in huaraches and save my Runamocs for the office.
