I've had the M11's for several years now. They are low volume, so I took out the insole to get more room in my toes. They are great all purpose boots - light, hike well, warm enough and climb fine. Some of the rubber rand around the toe has seperated on both boots and if I sometimes get small amounts of water in them. Not too big a deal though. Way overpriced, but that's them damn Italians for ya.
