Support and cushion working together in the name of maximum comfort.


Trusted Stability 

We've shifted our focus beyond the feet to the most injury-prone part of a runner's body: the knees. GuideRails keep you moving comfortably by keeping excess movement in check. 

Soft Cushioning 

Thanks to our patented BioMoGo DNA midsole, ultra-softness and durability aren’t mutually exclusive; ultimate sockliner enhances comfort

Enhanced Fit 

Enjoy comfort from heel to toe with a spacious yet secure fit thanks to an engineered-mesh upper and conformable embroidered saddle.

Additional Benefits:

  • A full-length Segmented Crash Pad accommodates any foot landing and delivers smooth heel-to-toe transitions.
  • GuideRails® support technology significantly reduces weight compared to prior versions.
  • The Ultimate Sockliner adds cushioning for a plush in-shoe feel.
  • The embroidered saddle and eyestay offer a modern look.
