The Prio is our best-selling "do almost anything" shoe -- running, hiking, working out, you name it.
With a durable upper, it provides a bit more protection.
The Speed Force is our lightest, "most barefoot" shoe.
More feedback as you step and a mesh upper that holds like a glove, you get a "barely there" experience.
The HFS is lighter than the Prio, more rugged than the Speed Force.
The HFS's sole has a tire tread-inspired sole that's made to handle roads and have extra traction.
The huarache-inspired midfoot and instep straps are "hiding" behind a protective welded material.
And the moisture wicking lining for extra comfort and breathability.
