Stability shoes have long been defined by what they prevent rather than what they provide. The Saucony Omni ST 23 flips that script. By pulling PWRRUN PB superfoam — the same PEBA-based compound found in Saucony's race-day lineup — into a true stability daily trainer, Saucony has built a shoe that guides your gait without dulling the ride in the process.

The midsole is the story here. PWRRUN PB handles the top layer for that bouncy, energetic feel, while a midfoot layer of PWRRUN foam and a modest TPU stability frame work underneath to keep overpronation in check. It's a setup borrowed from the Saucony Tempus, and it works because the correction feels like a gentle nudge rather than a hard wall — your foot stays aligned without the shoe ever feeling corrective or clunky underfoot.

A durable XT-900 carbon rubber outsole with deep flex grooves keeps transitions smooth from heel strike through toe-off and holds up well over high mileage. The engineered mesh upper is breathable and plush, wrapping the foot comfortably without excess bulk. The Omni ST 23 works equally well as a recovery shoe, a long run workhorse, or an everyday trainer for runners who need support across a full week of varied efforts. For overpronators who have felt underserved by the stability category, this one is worth serious attention.

• PWRRUN PB is a lightweight, PEBA-based foam that delivers high energy return and a lively feel.
• PWRRUN is a firmer foam that underlies the PB core to gently guide the foot and counteract overpronation.
• TPU Stability Frame forms an arc of midfoot support between the foam layers.

OUTSOLE

• XT-900 is a carbon rubber compound placed in high-wear zones for durability and reliable traction.

UPPER

• Engineered mesh provides a soft and breathable fit.
