Karhu Fusion 2.0 Trainers - Grey - Size: 9

While the Fusion 2.0 features Fulcrum technology designed to aid the gait cycle, they are primarily marketed and designed as versatile lifestyle trainers for everyday wear rather than dedicated performance running shoes.

The Fusion 2.0 are described as having a true-to-size fit for men and women. It is recommended to order your usual shoe size. If you are typically between sizes, consider trying a half-size up or down based on personal preference for fit.

The uppers are constructed using a combination of premium suede, leather, durable mesh, and ballistic nylon for a blend of style, comfort, and resilience.

Yes, they feature a grippy rubber tread outsole specifically designed to offer excellent traction and durability across a variety of terrains.

Yes, for suede, it is best to use a specialized suede brush or eraser for dry dirt and scuffs. Avoid getting the suede excessively wet, and consider using a suede protector spray to maintain its condition and prevent stains.

Karhu's Fulcrum technology is integrated into the sole to guide the foot through its natural running gait cycle. This aims to reduce impact on joints and improve overall efficiency and comfort during wear.

While the trainers offer some protection, they are not waterproof. The suede and leather materials can be affected by heavy rain. Using a waterproofing spray can offer additional protection, but caution is advised in very wet environments.

This can sometimes occur with new shoes. Try inserting a powder-free sock liner or talcum powder inside the shoe to reduce friction. Ensure the laces are not overtightened.

Check if your gait has changed or if there is an underlying issue with foot mechanics. If the wear is significant and affects comfort or stability, consult a shoe specialist.

For minor scuffs, use a suede eraser. For more significant discoloration, particularly from water or stains, immediate cleaning with appropriate products for suede and leather is recommended. Always test cleaning solutions on an inconspicuous area first.

The EVA midsole provides responsive cushioning. If it feels significantly less effective, it may indicate that the shoe has reached the end of its optimal lifespan for comfort and support.
