This shoe was gently tried on and shows slight signs of use. Newly formulated PWRRUN foam packs in more responsiveness with a softer feel than most other EVA formulations, so it delivers a livelier sensation than what stability-seeking runners are accustomed to | The tonal medial TPU guidance frame and 3D-engineered fascia in the upper both help deliver 360 degrees of stability while disappearing into the design of the shoe for a clean overall look. | FORMFIT addresses the collective constructions that help our shoes wrap and fit around your entire foot, and the Guide 14 has been streamlined to achieve more comfort with less bulk. | Runners will primarily notice this in the enhanced heel fit and a generally lighter feel on foot (11773/109)
