2026 Atomic Redster TX 100 Ski Boot

Description & Features

Built to power the next generation of ski racers, the Atomic Redster TX 100 LC combines pro-level features with a junior-specific fit and flex. With a 100 flex index and a 96mm performance last, this boot delivers the control, precision, and responsiveness young athletes need to push their limits on course.

The TX-specific wall thickness and Power Chassis reinforce the shell for optimal energy transfer and reduced sole flex, while the Anatomic Toe Box and 0° sole canting promote a balanced, neutral stance. Memory Fit shell customization ensures a dialed-in fit, and the Grind Grid and Depth Guide Boot Board allow for personalized stance tuning.

The low cuff design is specifically engineered for smaller, developing legs, while Dual-Sided Cuff Alignment and Power Control let racers fine-tune their setup. Inside, the World Cup Gold Low Liner with a Redster Fixed Tongue and cuff lacing locks the foot in place, while the 3D Stretch Toe Box adds comfort and fit adaptability during long training days.

Complete with magnesium Elite Buckles, a 35mm Velcro strap, and a Redster Solid Sole built to withstand heavy use, the Redster TX 100 LC is the ultimate tool for competitive juniors ready to level up.

Technical Info

Formula Plastics

Engineered for consistency under pressure, Atomic’s Formula Plastics maintain a reliable flex across a wide range of temperatures—delivering predictable performance whether you’re training in the early season or racing in spring conditions. This advanced plastic compound gives athletes enhanced control, confidence at speed, and uncompromised power transfer in every turn—ensuring peak performance all season long.

Power Chassis

Atomic’s Power Chassis reinforces the connection between toe and heel, reducing sole flex by 31% for maximum power transmission. The result: improved edge-to-edge response and more efficient energy transfer directly to the ski.

World Cup Liner

Developed in collaboration with top World Cup athletes, Atomic’s World Cup Liner delivers elite-level fit and performance. Crafted with a supple, one-piece microfiber outer and minimal seams, it molds precisely to the foot and boot shell for a race-tight feel, exceptional comfort, and maximum power transmission.

3D STRETCH TOE BOX

Asymmetrically shaped for left and right, the 3D Stretch Toe Box takes first fit and customization potential to the next level. It is Big Toe Friendly construction that maximizes the liner’s available length allowing for a little extra stretch when important millimeters are required to achieve the perfect fit.
