KARHU Fusion 2021

Features

The Karhu Fusion Ortix 2021 delivers unbeatable cushion and fast transitions to your everyday runs.

Built on top of Karhu’s unique AeroFoam midsole, the Fusion Ortix 2021 is lightweight and more temperature resistant than shoes built with EVA midsole foam. Maximum cushioning in the forefoot creates super-soft landings while an added propulsion unit energizes take-offs.

A shortened, 3/4-length Fulcrum embedded in the midiole of the Fusion Ortix 2021 concentrates cushioning toward the heel and midfoot, creating a responsive rocker that stabilizes each step and pushes you forward.

The upper is constructed from Karhu’s super-breathable, lightweight Ideal Knit mesh that supports your foot on top of the midsole for an all-around comfortable fit.
