I train regularly in the Vibram 5 fingers and have bought these shoes for racing, speed training and long runs. They are incredibly light (they feel almost as light as the 5 fingers) and allow me to run with the same shape as the Vibrams. The shoes are very spacious in the toe area and quite comfortable. I've used them in several races and they've held up well so far. The padding on the underside is starting to wear out a bit, but it doesn't look like more than normal wear and tear. My only complaint is that I feel like the arch support is too much. However, this is the best Vibrams alternative for more intense runs that I have found and I would recommend it to anyone looking for a lightweight zero drop shoe.
