After you've chomped up all the pow in-resort, go gobble up the pristine backcountry in the ever-accommodating and hard-charging Rossignol Women's AllTrack Pro 110 Ski Boot. Armed with Sensor Grid external shell enhancement that means improved, precise wrapping, torsional rigidity, and powerful energy transmission, plus an OptiSensor 3D liner that locks you in with secure comfort and a three-key fit, this boot makes no compromise in performance. But it brilliantly sheds weight, allows easy entry and exit, and features ski-walk modes that deliver exceptional downhill performance and wide-opening, hiking comfort. Because while the resort offers plentiful options, you don't settle for second tracks. Rossignol's AllTrack series of boots combines the response and performance of on-piste ski boots with the versatility and light weight you need to access the backcountry. The Women's Pro 110 is the stiffest, most performance-oriented boot in the line; the 'Pro' designation means it is built around a 100mm last for skiers with feet of medium width and volume who are looking for a snugger performance fit.
