Back in 1996, the Fusion was the top running shoe in the Karhu assortment and to bring it back from the archives, Karhu worked with the original designer to give it a refreshed look. The sole unit and upper measurements were revised to make the silhouette more stylish, but original details like the tongue label, rubberized collar print and "M-logo" lacing were kept. The Mount Saana pack comes in cool fall foliage colors as seen in the Saana landscape and appearance. The upper consists of a mix of pig skin suede and water resistant leather. To refresh this version of the Mount Saana pack, Karhu adds a new hiking lace design and updated the foot bed inspired by the wooden staircase leading to the mountain top.
