The Fusion 3.5 is optimal for daily running and long distances on asphalt. If you're looking for a fast racing shoe, trail shoe, or a Karhu model with more cushioning, consider:
Karhu's patented Fulcrum technology places a rigid element in the midsole that acts as a lever, transferring weight from the heel to the toe more efficiently. The result: less muscle fatigue, smoother transition, and greater lateral stability compared to shoes with only foam. Ideal for runners seeking control without sacrificing comfort over long distances.
