The Madshus Redline Skate F3 Stiff is a World Cup-level skate ski built for soft, slow snow, delivering fast acceleration, efficient V2 technique, and strong energy return.

The Redline Skate F3 Stiff are World Cup quality skate skis built with one goal in mind: to get you to the finish line first. The F3 Stiff model is made for softer, slower conditions.

Both the F2 and the F3 models feature the unique Tuned Dynamic Response technology to provide phenomenal energy return and maintain optimal gliding surfaces throughout the entire duration of the ski push-off phase, thus improving snow feeling and maintaining speed.

The major differences between the two models lie in the pressure zones and the groove length. 

The F3 Stiff is built with shorter pressure zones to prioritize acceleration, and a revolutionary tail-only groove that improves biomechanical efficiency by allowing skiers to maintain double skate (V2) technique much further into uphills, especially in softer and slower snow where it is more difficult to maintain momentum.

Recommended ski length:

Your body weight is the key factor when choosing the length (size) of your skis. If you fall between two weight ranges, it is advisable, as a beginner, to opt for the shorter skis. If you are an advanced skier, the longer skis are recommended.

Also pay attention to the descriptions: Soft, Medium, Hard/Stiff. These specifications further refine the weight ranges.

172 cm = 45–60 kg
177 cm = 55–70 kg
182 cm = 65–80 kg
187 cm = 75–90 kg
​​​​​​​192 cm = 85–100+ kg
