CREATED BY THE RUNNER, FOR THE RUNNER: At Karhu, we know every runner has unique feet. That’s why the Fusion is built from a growing database of over 2 million 3D scans taken from runners’ feet to build a truer-to-size choice for maximum comfort and agility.
FOR PERFORMANCE ORIENTED ATHLETES: The Men’s Fusion is ideal for neutral-footed runners. Thanks to its plush yet propulsive ride, the Fusion is the best shoe for athletes on the days you’ve planned up-tempo workouts—or when you’re prepping for your next race.
EXPERIENCE PREMIUM COMFORT: With the Fusion, you get a highly-cushioned AeroFoam midsole that protects your underfoot while the anatomical lacing system creates a secure fit you can adjust to your foot.
DESIGNED FOR MAX AGILITY: The Fusion features a shortened fulcrum and a propulsion unit for quick turnover, an efficient stride and even quicker transition—a huge advantage on race day.
SUPPORTIVE & BREATHABLE FIT: Includes an AeroFoam midsole and Ideal Knit mesh construction for better breathability and stronger support for your feet, with stretch when you need it.
