Have made it through 1 blizzard & 2 major snow storms, a few minor ones, and an ice storm with my new boots.  Great, warm, comfortable boots; dry happy feet!  They are not boots for the frail footed, these are serious, cool boots.  Wearing 4 days a week, awaiting a thaw!!  Great no slip soles!  Great on packed, slippery snow and even ice.  Highly recommend.  I read mixed comments about sizing; I found them to be true to size.  Ordered my normal size; they fit perfectly.
