These women's carbon-fiber racing shoes weren’t made for chasing personal bests. They were made for smashing them.

With lots of ultralight, springy PWRRUN PB foam cushioning and Saucony's signature S-curve carbon fiber plate, running at top speed feels easier, so you get to the finish line faster.

SPEEDROLL Technology—a larger wedge of soft foam in the heel and a firmer feel in the forefoot—propels you forward with the feeling of continuous momentum, so you can run faster, not harder.

FORMFIT wraps the foot in 3D comfort and ensures a personalized, locked-in fit for optimal performance. The mesh upper, inspired by Saucony's Endorphin track spike, is as light and unobtrusive as you'll find.

Heel Support Frame steadies the heel through the whole gait cycle. Hard-wearing carbon rubber is limited to strategic placement on the outsole to minimize weight.
