Head to the local park's trailhead, or make your own tracks off your back porch. The Alpina Men's TR 50 is a warm, comfortable cross country skiing boot that guarantees fun trails are on the horizon. The mid-flexing sole has an athletic-shoe fit, so they're comfortable for walking and stiff enough to handle Nordic skis. Thinsulate insulation seals in heat, while a lace cover keeps snow out and prevents the laces from getting iced up. The TR 50 Nordic Boot is a perfect boot for anyone who skis in cold climates or has chronically cold feet. They're compatible with Alpina and Rossignol NNN Touring bindings. Bottom Line: Boots so warm and comfy you'll ski twice as much as last year.
