The Olympus Mon has received a major overhaul for 2019. Being that it used to be comically massive/heavy the new version has been significantly stripped back, yet retains the warmth. With a dial to adjust the fit and two inner boots it really is something completely different and unique. A reflective Primaloft lining across the sole provides further warmth, as does the thick EVA sole. Carbon honeycomb midsole which retains warmth. Weighing in at 1050kg per boot, these are extremely lightweight!
