During a turn the left and right skates are sliding on the ice with different radius. The special asymmetric 3D design of the left and right edges of XCBlade helps this divergent movement requirement, optimizing the energy consumption on skating. Turning is optimized with XCBlades, allowing the player to gain up to 4-15% movement energy (per match) compared to traditional blades.
This energy saving can be crucial in the late stages of a match during the endgame.
