If you measure the value of your ski outings based on the number of runs you make in a day, the Head Women's Edge+ 10 HF is the perfect choice for your upcoming season. That's because it combines intermediate-level boot flex with exceptionally warm HeatFit insulation for all-day comfort and performance. Inside you'll find a plush, self-shaping footbed and HeatFit thermal lining with fleece that offer exceptional warmth. These innovations are the result of extensive thermographic tests on a new line of warm insulating materials--and the new Head Edge+ boots are much warmer than seasons past. If you ski in exceptionally cold climates, the Edge+ 10 ONE HF liner is ready for a battery-powered heating system, but that's sold separately. The Edge+ 10 ONE HF also features a distinct stabilizer frame that helps reinforce the shell, adding more stability and energy transmission performance between your foot and the ski binding. This stabilizer is specifically matched to suit intermediate skiers. Beneath everything is Head's Grip Sole, a soft rubber insert that makes walking easier and safer than conventional ski boots. It works with the SoftWalk Heel to help you maintain your balance and control on slippery surfaces--like all that packed-down snow on the pedestrian trails around the day lodge.
