Karhu Fusion 2.0

KARHU Fulcrum: Innovative midsole technology designed to maximize the efficiency of your movement. Unlike conventional cushioning systems that merely absorb energy, Fulcrum works like a lever, harnessing the body's natural energy to smooth the transition from heel to toe. This technology reduces vertical oscillation (bouncing) and helps keep your foot in a straight line, saving your energy and reducing foot fatigue. The result is a balanced, stable and extremely comfortable stride, whether you're running off-road or just cruising the city in sneakers.

Suede: Leather with a characteristic brushed finish and a soft, velvety texture. Unlike smooth leather, it is produced from the inside of the leather, which gives the material an unmistakable softness and suppleness. The main advantages of suede footwear include high breathability and the ability to adapt quickly to the anatomical shape of the foot, making the shoes comfortable from the first wear. Suede stands out for its depth of colour and gives the shoes a premium look. In order for the material to retain its properties and beauty, regular impregnation is recommended to ensure protection against moisture and dirt.

Polyurethane foam: (PU) is a high-performance midsole material known for its exceptional dimensional stability and durability. Unlike lighter foams, PU does not break down even after hundreds of kilometres and retains its cushioning properties. Thanks to its higher density, it provides excellent stability and support, which is crucial for heavier runners or hikers with a load. It's the ideal choice for durable outdoor and work footwear where foot protection and maximum resistance to mechanical wear is a priority.

Rubber: The rubber outsole provides excellent grip and durability on a variety of surfaces. Thanks to its elasticity, it absorbs shock, increasing comfort when walking or running.
