My feet sweat so I like the Klim boots with the gore-tex. I've had comfier boots but usually with the bulkier feel in the foot-wells. I don't like the feeling of getting my foot hung during a get-off and the Klim and Columbia boots I've had fit my footwells better than HMK's. I had some Burton's that had awesome ankle support but the dubbed off toes for snowboarding and the stiffness caused me to fumble my side to side running board switching a lot.
