The Alpina Eve 75 Heat is an excellent ski boot for the intermediate to advanced skier who has a medium to wide forefoot and medium to wide leg shape. Alpina uses a Women's Specific Fit with a narrower heel pocket to prevent your heels from slipping around in your boots and added control over your skis. A VCP (Volume Control Plate) allows you to tinker with the fit by swapping your left and right bootboards for a more dialed in fit, without the need for a bootfitter. The VCR (Volume Control Regulator) has an adjustable spoiler in the calf area that also makes for an easy adjustment in a tricky to fit area for some women. Alpina's InTemp Heating System is fully integrated into the liner by having heating coils that encase the foot. Three different temperature settings allow you to regulate the temperature inside the boot. An Included USB Charger connects to a hidden battery pack to provide heat for your duration on the mountain.
