A new lightweight breathable mesh upper, a new sole inspired by tire treads, a silky, moisture-wicking lining, protected tension straps... it all comes together to create your new favorite road running shoe, the HFS. Of course, we know you'll be doing a lot more than just running on your favorite roads with the HFS (and we can't wait to see photos of what it will bring you and what you'll be doing with it!). It could be for the "highly flexible sole" that lets your foot move naturally, or the look on your face when you put it on - "Happy Face Shoe" - or the way you run with it with a "High Frequency Stride", or what you exclaim when you put it on and feel the comfort and lightness: "Holy ___ ___!" There are as many possible answers as there are things you'll do with the HFS. WHY YOU'LL LOVE HFS: Natural FIT - a wide toe box allows your toes to extend, spread, relax and function naturally. Natural MOTION - the HFS is flexible enough to allow your feet to bend, move and soften as they were meant to. The "XERO-drop" design (heel not raised) allows correct posture, and it's built flush with the ground for balance and agility. Practically new, barely soiled on sole.(picture)
