The Atomic Redster FIS 150 ski boot is a full-on racing machine, developed by and for skiers at the top of their discipline. It has an ultra-stiff 150 flex and Carbon Spine that’s up to six times stiffer than normal plastic, which means every turn you carve can be extremely precise and aggressive. The sole is lifted like the FIS 170 (so you’ll need an authorized Atomic dealer to bring it back to DIN standard). The FIS 150 also features a narrow 95mm last for an authentic race-room fit and super-precise foot hold. Our unique Memory Fit technology gives it a truly personalized fit. And the Rotational Cuff, Micro Cuff Alignment and three interchangeable Flex Frames allow you to tune your boot to your discipline, style and physique. The ideal custom ski boot for serious racers.
