More information about Karhu Men's Fusion 4.0 Running Shoes

ENHANCED COMFORT & BREATHABILITY: The Karhu Fusion 4.0 features an upgraded IdealKnit mesh upper in a trendy brindle pattern, enhancing breathability and keeping your feet cool and soft. Paired with superior AeroFoam cushioning infused with nitrogen, it offers exceptional rebound and support for a plush, cushioned ride.
SIZE RECOMMENDATION: For the foremost fit, we recommend sizing up a full size compared to your regular size.
RESPONSIVE RUNNING: Designed for peak performance, the Fusion 4.0 offers a smoother transition and enhanced toe-off thanks to its increased toe spring and rockered midsole shape. The innovative deflection channel in the midsole absorbs impact effectively, reducing strain on joints and enhancing your running experience.
HIVO: Available in both medium width and HiVo (Wide). More than just “wide,” HiVo provides a higher volume upper to accommodate thicker or broader feet, and feet with common problems appreciate bunions, calluses and corns.
