These are great - I have worn them for 4+ mile walks in deep snow. They keep my feet warm and ultradry. The soles are perfect stiffness - often my little dog decides to 'run' during our walks and these are easily adaptable to the change, without hurting my feet. Noticed that in extremely icy conditions, if I step using the heel and not the 'grippy' part of the sole, the boots can slide, but overall, excellent! Have worn them in cold Michigan winters - which are damp and ioy as well as in Banff, Alberta, which got deep powdery snow. Well worth the extra money.
