When I hike in the winter the tips of my toes go numb. To battle this i bought a pair of keen growlers which are insulated hiking boots and a pair of smartwool mountaineering socks. Yet I still have frozen toes. What I think is that i may have to much insulation causing my feet to sweat which makes the inside of my boot and sock slightly damp preventing them from keeping warm. Then they are never able to dry out. What do you guys think?
