Sneakers - KARHU - Fusion 2.0 - Green - Blue - Trainers

While the Fusion 2.0 offers good cushioning for general wear and light activity, it is not specifically designed as a high-performance marathon running shoe. For marathon running, specialized running shoes with advanced technical features would be more appropriate.

Refer to the KARHU sizing chart available on their official website or from reputable retailers. Generally, measure your foot length from heel to toe and compare it to the provided size guide. The provided size is UK 6.5.

The materials used offer some resistance, but they are not waterproof. Prolonged exposure to heavy rain may lead to water penetration. It's advisable to protect them with a suitable water-repellent spray, especially for suede components.

'Fusion 2.0' indicates a second iteration or updated version of the original Fusion model, likely featuring design improvements, material updates, or enhanced comfort features based on feedback and advancements.

Cleaning frequency depends on usage. For daily wear, a quick wipe-down after use is beneficial. For heavier dirt or stains, clean as needed using the recommended care instructions to maintain their condition.

The Fusion 2.0 typically features a combination of suede, leather, and mesh for the upper, with an EVA midsole for cushioning and a rubber outsole for traction.

Loosen the laces and re-tie them with less tension. Consider using thinner socks or wearing the shoes for short periods to allow them to break in.

Use a suede brush to gently lift the nap and remove surface dirt. For stubborn stains, consult a specialized suede cleaner.

Check the outsole for embedded debris like stones or mud. Clean the outsole with water and a brush. If the tread is significantly worn, consider replacement.

Ensure the original insole is correctly positioned. If persistent discomfort occurs, consider replacing it with an aftermarket insole designed for cushioning or support.
