The Atomic Redster TR 3 delivers elite-level race performance in a more forgiving 110 flex, making it ideal for developing racers or lighter athletes who still demand precision and control. Built around a 93mm Narrow Racing Last and featuring an Anatomic Toe Box, it provides a secure fit with just enough space in the right places to enhance balance and positioning. The shell and cuff are crafted from durable polyurethane (PU) for a responsive, progressive flex that efficiently channels energy to the ski. Inside, the World Cup Race Liner and Ankle Retention System ensure a race-ready fit, while the adjustable AFS Tongue fine-tunes comfort and pressure distribution. The Power Chassis reinforces the sole for maximum torsional stability between the toe and heel, keeping every movement tight and controlled. This is a boot built to push limits, without overloading lighter racers.
