I just completed a 100km trail race in Australia using these shoes. In the last 7 months I've logged over 2,500km's in training + the race and only now have they died.
I worked towards a more minimalistic, neutral shoe over the last couple of years and struggled to consistently find a solution from the other main stream brands. I love that Ons don't follow the same model off other manufacturers where they design obsolescence into their business model i.e. their models don't change every 6 months which is frustrating when you find a shoe that works for you only to find that its no longer available when you need to replace them.
NOw. These are not a trail running shoe as I discovered a week ago. My feet have forgiven me and, ultimately, they got me through what was a technical and rugged trail. I've just ordered a replacement pair + a pair of the Ons trail shoe :-)
Lightweight, comfy, durable and well priced. Thank you!
