I have never in all my years skiing complained of my feet being cold. Just this year my big toes (and only the big toes) are frigid! My boots are 2 years new, fit flawlessly, and are not tight across the toes or toe box. My socks are the same as always: smart wool & icebreakers. I wear a single pair, no wrinkles, and nothing extra tucked into the boots. Don't believe its medical/circulation related as it only bothers me when I ski. Perplexed here.....suggestions?
