F.K.T means “fastest known time”. Columbia MONTRAIL F.K.T. W women’s running shoes for long trails are a celebration of the Montrail’s trail roots. The seamless textile upper is laminated for maximum breathability and support. The sock-like construction with an ingenious double lacing system provides unrivalled fit and fixation. The external TPU heel reinforcement “locks” you to the ultra lightweight midsole that provides optimal cushioning and excellent comfort. This latest model features an 8mm drop (18mm heel height/10mm toe height) and a midsole made from mid-weight EVA material with an integrated protective TrailShield™ platform lying on a soft, reactive TPU foam that absorbs the shocks and adds more stability to your feet. Rubber sole with 4mm pattern provides durability and good grip on dry and wet surfaces.
