He suggests to avoid perspiration unduly dampening your boot, the absolute best way to dress is to use a polypro sock to wick moisture away from your foot (for comfort) then layer on an impermeable barrier, ie. plastic bag or equivalent!
I've never tried that skiing, but the physics is fairly sound. I wear a Coolmax liner under Smartwool mountaineering socks, and I dry my boot liners every night. No problem with cold.
When cycling in the cold weather, I wear neoprene gloves and over-boots. Neoprene is closed-cell foam that insulates and does not allow air through. My hands and feet get very soggy, but they rarely get cold. If the water doesn't have a chance to evaporate, and if there's some insulation between the water and the environment, hands and feet should stay warm.
