ON SALE - Head to the local park's trailhead, or make your own tracks off your back porch. The Alpina Women's TR 50 is a warm, comfortable cross country skiing boot that guarantees fun trails are on the horizon. The mid-flexing sole has women's specific fit. Alpina designed the boot to promote circulation, which prevents cold feet. 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 women who ski in cold climates or have chronically cold feet. They are compatible with Alpina and Rossignol NNN Touring bindings.
