Karhu Mestari Run 1.5

The Karhu Mestari Run 1.5 is a premium max-cushion road trainer built for runners who want a protective, efficient ride that stays steady when fatigue sets in. Designed for neutral strides as well as mild to moderate overpronation, it pairs a boosted AeroFoam midsole with Karhu’s Fulcrum geometry to create a smooth, rolling transition that keeps you moving forward. Up top, the refined IdealKnit mesh balances breathable structure through the midfoot with a more forgiving, comfort-first fit in the toe box.
