Flow Fulcrum Trail Running Shoe - Men's

With the Karhu Men's Flow Fulcrum Trail Running Shoe firmly fixed to your foot, you've got a damn fine chance of finishing the fire and water 25K in Nicaragua without any tell-tale signs of slipping, falling, or otherwise being manhandled by a jungle volcano. The waterproof side vamp wall shields your foot from mucky, marshy goo on the wet side and counter-directional T-lugs let you scramble, sure-footed, over arid scree fields on the dry side. Even if you're not ready to race up mountains, the Flow Trail takes on techy single track or gravel-packed paths with stunning ease and stability.

Air mesh gives you foot some fresh air without leaving your toes exposed to trail insults. An abrasion-resistant and waterproof rand of ballistic material circles your foot for protection when traversing extreme and variable terrain. Both the collar lining and the shoe lining suck up sweat so your foot isn't felled by festering blisters or wince-worthy hot spots. The compression-molded EVA insole puts some spring on your step while helping the Flow feel good the instant you slip it on.

The EVA love continues through to the midsole, where injection-molded EVA softens the blow of your footstrikes without sacrificing any spring. Directly centered for your neutral stride, the compression-molded, 70 durometer EVA Fulcrum smooths your gait cycle and propels your forward, while economizing your running movements. As a result, you go faster, farther, and all for the same amount of energy input. T-shaped lugs are situated so you have great grip up hills, down hills, across snow-packed streets, and when traversing slightly submerged creek rocks. When your limited attention span demands the variability of off-road running, let the Flow Trail take you to a place where you can taste it all: mud, blood, sweat, and scree.
