REDSTER TR F4

The Atomic Redster TR F4 is an intentionally constructed race boot, with a strong 130 flex and thick, supple shell material, ideal for bigger athletes who find the 150-flex boot a touch too stiff. This boot uses our most stable and temperature resistant Formula Pastics. It’s still got the DNA of a World Cup race boot – with features like an anatomical fit through the toe box, a top-of-the-line World Cup Race Liner, and a narrow 93mm Racing Last. Power Chassis underfoot adds rigidity. Plus, you’ve got the adjustable Redster AFS Tongue, which can be positioned for different instep heights, and the Ankle Retention System on the liner for a solid heel hold and increased responsiveness. The Redster Solid Sole underfoot provides a precise, sensitive interface between the boot and alpine bindings.
