Most people don't make a routine out of a physically demanding activity that requires persistent effort to get any good at. Even fewer do that just for fun. It's like we've always said, runners aren't normal. We designed the 860 to keep up with the demands placed on shoes by the dedication of the stability-minded every day runner. The latest entry in the series, the Fresh Foam X 860v13, augments the pinnacle cushioning experience of Fresh Foam X with a supportive medial post to provide essential stability. Built for reliability over the long haul and sustained comfort over all distances, the 860 is a true go-to shoe.
