The stability of the ½ length Fulcrum unit is able to reduce pronation in the heel and through the mid foot, while the flexible forefoot provides a natural ride of a neutral shoe.
This model provides similar guidance as Karhu Ikoni or previous versions of Karhu Flow and slightly less forefoot stability than Karhu Synchron or Karhu Fast. This model suits a normal volume foot.
A high volume foot might be better suited in a Fusion or Synchron Ortix, or size up ½ in the Fluid.
