The Rossignol AllTrack Pro 130 is a high powered boot for experts with a WTR Sole that best fits a medium to narrow forefoot and medium to narrow shaft of the leg. Rossignol's Sensor Grid Technology beefs up the torsional strength of the shell to give you precision and power with each turn. The Posi-Block Ski/Hike Switch gives you a wide range of motion for hiking and skinning you way uphill to a burly peak, while maintaining a trusted downhill performance. The AllTrack 130 Pro comes complete with the Optisensor 3D Liner that wraps your foot very precisely, and maximizes the interaction between the foot, liner, and shell. If you want power in a boot that you can hike in, the Rossignol AllTrack Pro 130 is the boot for you. Rossignol All Track Pro 130 Ski Boots Mens | Size 25.5
