This shoe was made for SF running.  Designed for road-to-trail running, this is the shoe you want to wear for those adventure runs where you might pop off road on a random trail or two.

High performance meets ultra-sustainability.

Created through a process of advanced supercritical foaming, each pair of CircleCELL™ midsoles is made from up to 20 pounds of organic waste and residual biomass.  Despite its sustainability credentials, CircleCELL™ delivers energy return on par with PEBA, with almost double PEBA's lifespan.

All terrain traction

Mount to Coast VersGrip™ is engineered to deliver exceptional traction, confidence and durability across all terrain, so you can run to the trails from your front door without ever missing a step.  Worried that a road shoe will be out of its depth on trails?  VersGrip™ has got your back.  This is optimal performance for real-world situations.

Tune in, don't drop out.

The TUNEDFIT™ Dual Lacing System offers separately customizable fit for the forefoot and midfoot.  Because we know that in the ultrarunner's pursuit of distance, feet can swell and change shape, and having a shoe that can adapt to those changes on teh fly can be the difference between minor discomfort and injury.

An upper for any environment

The H1 features a dual-zone upper.  Across the top portion, the shoe is engineered with jacquard for adaptive fit + comfort, while the lower part is crafted for exceptional durability with a high-performance woven fabric, reinforced with aramid fibers that are five times stronger than steel.
