Columbia Montrail Fluidflex FKT II

Women’s 215 g (7.6 oz.) Men’s 270 g (9.5 oz.) Drop ratio: 4 mm $140

A few years ago, venerable outdoor brand Columbia picked up Montrail, a respected player on the trail circuit. Together, the Montrail DNA – lighter, flexible shoes focused on the trail – lives on. The Fluidflex FKT II is aptly named (FKT standing for “fastest known time”). It’s a light and responsive ride for faster running on the singletrack.

The midsole is regimented into a series of EVA zones that move nicely in unison, even on rooty and rocky terrain. The three flex grooves cut into the mid- and forefoot allowing the foot to react to ground contact naturally, creating a nimble ride. The upper is mostly a layer of breathable mesh, held together with glued-on overlays, finishing off this lightweight and highly flexible package. If you’re looking for a shoe that will respond to aggressive movement, the Fluidflex FKT II is a great option.
