The Atomic Redster TR F4 is a precisely engineered race boot straight from the World Cup, designed for larger, stronger athletes. With its 130 flex, it delivers a stable yet more forgiving feel than a 150 model, making it the perfect balance of power, control, and flexibility. The shell, made from robust and temperature-resistant Formula plastic, ensures consistent performance in all conditions. Its 93 mm narrow racing last and anatomical toe box provide maximum precision, comfort, and balance. The World Cup Race liner with Ankle Retention System locks the ankle securely, offering a reactive and confident skiing experience.
The Power Chassis reinforces the midsole for outstanding torsional stiffness and grip. The adjustable Redster AFS tongue system allows fine-tuning of instep fit, while the Redster Solid sole creates a precise interface with bindings for direct power transfer. With the 55 mm Professional Dual Strap, every ounce of energy is transmitted into speed and stability. Don’t wait – with the TR F4, you step into World Cup technology built for control, precision, and power in every turn.
