I ordered the online and upon receiving the boots and noting how light and thin they really are, I was skeptical of the insulating claims. However, on the first day I rode my bike for an hour in -25 Celsius with only thin socks on I was amazed. Not even a hint of a chill, toasty warm feet. This prompted me to do some research on the nanotech insulation. It's amazing stuff!
I highly recommend these boots for cold, although I have yet to find out how durable they will be in the long haul.
