What's New About the Vaporfly 3? - An updated thin outsole rubber uses less material without sacrificing durability, which helps reduce outsole weight and thickness. This allows for extra millimeters of ZoomX foam underfoot and a smoother transition through your stride. 

Light padding on the tongue helps reduce lace pressure at the top of your foot. A new Waffle outsole pattern with perforations saves weight and delivers multi-surface traction in various weather conditions.

Offset heel seam helps reduce friction in the heel area.
