Bob I too bought a pair last fall, for early fall weather up here, but was very suprised how warm they were. I have worn them all winter ice fishing and sleding(skidooing) and been very impressed. I must admit the for the price I paid I didn' t have big expectations for this boot. Having logged some trail miles and wearing them in the cold, I would say they are great boot and for the price ain' t much better that I have found. The one thing I really like is the ease to get into these boots (compared to other gortex bootie style' s i have used) and their light weight.
