Mens Karhu Fluid 5 MRE :: The versatile Fluid 5 MRE, which stands for Maximum Rolling Effect, features an asymmetrical Fulcrum lever. This lever propels the runner forward while the additional medial volume ensures a supportive platform. The softer forefoot midsole allows for a smooth transition to the push off phase. The upper utilizes an integrated lacing system for a personalized fit in the midfoot while the forefoot mesh allows for toe off without any obstructing overlays. Each model comes with a new precision molded insole that hugs the runners foot for a comfortable step in fit and feel. The midsole is made from two types of foam: a Protect Foam compound improves shock absorption while the Propel Foam used in the Fulcrum encourages the rolling effect.
