Karhu Fusion XT

Leather: A traditional natural material obtained by processing animal skins, valued in the shoe and haberdashery industry for its inimitable combination of durability, breathability and aesthetics. Thanks to its unique fibrous structure, the leather is able to adapt perfectly to the anatomy of the human body, ensuring high user comfort. It is a "living" material that breathes naturally, absorbs moisture and acquires a characteristic patina over time. Depending on the processing method (smooth leather, suede, nubuck), it offers different degrees of resistance to external influences and different surface textures.

Textile: Textile uppers are a lightweight and highly breathable upper construction solution that uses woven or knitted structures of natural and synthetic fibres. This type of upper is valued in the footwear industry for its extraordinary ability to adapt to the shape of the foot, minimising the formation of blisters and ensuring high user comfort. Thanks to the porous structure of the material, textile uppers allow for efficient heat and moisture dissipation, which is crucial for maintaining an optimal microclimate even under increased physical stress. In addition, modern textile processing technologies allow reinforcement zones to be integrated directly into the knit, achieving an ideal balance between stability and flexibility.

Rubber: It is one of the most widely used materials for the production of soles due to its high mechanical resistance and durability. The main advantage of rubber soles is their excellent grip (traction) on different types of surfaces, which minimises the risk of slipping. The material is naturally flexible, waterproof and effectively absorbs shocks during walking. Depending on the compound, the rubber can be either soft for better contact with the ground or hard for maximum abrasion resistance on rough terrain.
