Montrail’s Fluidflex ($90) will be release in January 2013 according to Running Warehouse. This flexible, yet beefy trail runner offers a FluidFoam midsole with a minimal 4mm offset. The full-length compression-molded foam (11mm forefoot and 15mm heel) is engineered with flex grooves for natural motion. The upper looks very clean with minimal overlays. The Fluidflex is part of Montrail’s new Fluid line which also includes the FluidFeel (a hypbird shoe focused on road duty) and the FluidBalance (a stability road/trail shoe).
