The shoe fits true to size, perfectly snug with just the right amount of room in the toe box to not feel cramped. I have several runs on the south, snow free sides, of mountains here in AK. The trail conditions have ranged from steep dry dusty slopes, scree, mud and some snow and ice. The grip is phenomenal! I have not slipped out once either on the ascents or descents. Water quickly enters the fabric uppers, but then almost as quickly evaporates out. I have yet to get back to the trailhead with wet feet. Incredible tools for their intended purpose.
