The men's KARHU Mestari Run 2.0 HiVo Black / Black is a max-cushioned daily trainer built for neutral runners and those with early to mid stage overpronation. Built for comfort, consistency, and the smooth “roll” runners love.
At the core is our reformulated AeroFoam NITRO, engineered for better rebound and a softer, more forgiving feel on daily mileage. The Mestari Run 2.0 for men also features an encapsulated Fulcrum combined with an 8mm heel-toe offset to maintain a stable, effortless transition from landing to toe-off. A new amplified toe spring creates an even smoother forward roll, while the updated IdealKnit mesh brings structured stretch through the midfoot for secure comfort on longer days.
At KARHU, we understand that every runner’s feet are unique. That’s why the men’s Mestari Run 2.0 HiVo is crafted using insights from our growing database of over 4 million 3D foot scans and accommodates the needs of runners with wider feet.
Designed for those who are in it for the long run, the newly updated Mestari Run 2.0 wide fit for men delivers a more cushioned, more responsive, and more fluid experience underfoot.
