Midsole

The midsole of this shoe is made of AeroFoam. This Karhu-patented material is lighter, more resistant to extreme temperature fluctuations, and more durable than traditional EVA foam. Using Fulcrum technology in the midsole, this shoe moves forward thanks to a balanced cushioning, providing more support. The propulsion plate will provide you with extra stability while running and also propels you forward.

Upper

Outsole

During running, the shoe offers good grip and traction thanks to the rubber outsole. Order the Karhu Fusion 4.5 and give your tempo and interval training a quick boost within a few days!
