The Men's Fluidflex F. K. T. II from Columbia is an ultra lightweight trail shoe, that is now even lighter. It consists of a seamless upper construction with a PU midfoot cage welded against open mesh for protection and support and an enhanced collar foam for comfort and a better fit. The FluidFoam midsole provides deep flex grooves for flexability, while patented FluidGuide technology is used to enhance midfoot stability. The Gryptonite rubber heel and forefoot provide 3-point lugs for multi-directional traction. Furthermore, the forefoot has TrailShield which adds protection.
