Are you looking for a shoe for fast training or even a race where you can show your strengths? Then the Karhu Fusion 4.0 running shoe is just right for you.

The Karhu Fusion 4.0 running shoe is a reliable neutral shoe that offers a soft and dynamic running experience. It features the most distinctive 'role' in the KARHU running collection. With a 6mm heel-to-toe offset, reactive AeroFoam cushioning and a compact Fulcrum, it provides a fast and efficient running experience, both at leisure and at high speeds.

The Fusion 4.0 remains a soft, powerful neutral shoe with a slim fit. The striped IdealKnit mesh upper provides a comfortable feel and increased breathability. Optimised geometry, including a reinforced toe suspension in the forefoot, provides a smooth transition and more lift when rolling. The nitrogen-impregnated AeroFoam midsole enhances rebound, while a deflection channel in the outsole absorbs shock and provides additional cushioning.

• Effective propulsion thanks to Fulcrum technology
