The Nordica Sportmachine 120 is the perfect option for bigger and more aggressive skiers who have a medium width forefoot and medium size shaft of the leg. Nordica's Infrared Customizable Shell allows an Authorized Nordica Dealer to heat the shell using a special lamp, and then expand the shell in key fit zones by pulling it out with an air compressor. The Tri-Force Construction has reinforcements on the spine and shell of the boot that improve your responsiveness and reduce torsional twisting of the shell. Nordica's 3D Cork Fit Liner utilizes cork in the heel and ankle pocket for a strong energy transmission, trusted heel lock and it can be molded by using heat. Primaloft Insulation keeps your feet extra warm when you are waiting for first chair on a deep January morning. An ACP (Adjustable Cuff Profile) allows you to tinker with the fit across your calf for a finely tuned fit. If you are an aggressive skier looking for precision and customization in a boot with a medium width fit, the Nordica Sportmachine 120 is a perfect option.
