Saucony Omni 23 ST Review: A Bouncy Stability Shoe With a Real Medial Post

Introduction

The Saucony Omni 23 ST is one of the surprises of the 2026 stability shoe market. It arrived with very little fanfare, quietly slipping out alongside Saucony’s more heavily marketed releases, and it deserves far more attention than it received. After roughly 70 to 75 miles of testing, it has earned a place as one of the most interesting stability shoes of the year.

What makes it unusual is the combination it offers: a full-length, full-height PWRRUN PB super foam midsole that feels genuinely soft and bouncy, paired with an aggressive medial post that extends through the TPU frame from the medial side toward the lateral edge. Very few modern stability shoes still carry a significant medial post, and almost none pair one with a bouncy super foam. The result is a daily trainer that stabilizes without feeling dead underfoot.

Who This Shoe Is For

The Omni 23 ST suits runners who want a soft, responsive, bouncy ride in a stability shoe, rather than the firm and dense feel that dominates this category. If you have missed the era when medial posts were standard and you want genuine structure on the inner edge without being aggressively pushed laterally, this is a rare find.

It is technically classified as a motion control shoe given the size of the post, but in practice it behaves more like a moderate stability shoe, occupying territory that the Saucony Guide line used to hold. If your stability needs are milder, the Hurricane or Guide may fit better, but if you want support plus bounce, this is the standout.

Main Strengths

The midsole is the headline. In a men’s size 10, the shoe specs a 43mm heel and 32mm forefoot for an 8mm drop, weighing 10.5 oz (298g). That makes it the highest-stack, lightest-feeling option in Saucony’s current stability range, matching the Hurricane 25’s weight while sitting higher off the ground.

The formulation of PWRRUN PB here is the best version of that foam outside dedicated super racing shoes. It is bouncy, soft, and responsive, and the ride rolls smoothly from heel to toe thanks to a well-shaped bevel and a lateral heel cutout that compresses nicely through the transition. It is not a true fast shoe, but it handled progression runs and up-tempo work well, and it has become a favorite for long runs. For runners seeking a stable marathon-distance trainer with genuine bounce, it fills a gap that the category has left open for years.

Durability has also been excellent. After 70 to 75 miles, outsole wear is minimal, and the midsole has retained the same bounce it had on day one. The upper is plush in the rearfoot with plenty of forefoot volume, the midfoot locks down securely over a thick, well-gusseted tongue, and the padded heel collar has been comfortable even against a sensitive Achilles, despite a stiffer heel counter.

Things to Consider Before Buying

Fit is the main watch-out. The forefoot is slightly snug in feel but generous in volume, which means wider-footed runners will likely love it, while narrow feet may find extra room that needs locking down. Some heel slippage appeared unless the heel was laced securely, and a few runners may want a lace lock for full security. The overlays add structure but can occasionally dip against the skin, so socks are advisable.

Stability is concentrated in the heel and midfoot. Because the midsole is soft, the forefoot offers less resistance to motion, so runners who need support under the forefoot should look elsewhere. The medial post is substantial enough to stabilize the soft foam, but this is not a rigid motion control shoe on the level of an ASICS GT-4000.

Buying Advice: How It Compares

Against the Saucony Hurricane 25, the Omni 23 ST is bouncier and more stable. The Hurricane blends PWRRUN PB with EVA, which softens the ride and reduces the sense of structure, since the EVA post compresses more than the TPU frame in the Omni. Runners who dislike medial posts but still want some bounce, a lower-volume feel, and a slightly wider upper may prefer the Hurricane instead.

The Saucony Guide 19 is the simplest of the three: a firmer EVA midsole, a lighter and more snug close fit, and a more traditional mild-stability ride. It is also the best walking shoe of the group, as the Omni’s bounce, while great for running, is more than many people want for walking and standing.

If you want a bouncy, responsive stability shoe with a medial post that can pick up the pace and handle longer efforts, the Omni 23 ST is the pick. If you prefer a milder, firmer, more conventional experience, the Hurricane 25 or Guide 19 will serve you better.

Conclusion

The Saucony Omni 23 ST is the most exciting version of this line in memory. It keeps the medial post that so many stability shoes have abandoned, wraps it around a genuinely bouncy super foam midsole, and delivers a smooth, comfortable ride that works for daily training, long runs, and up-tempo days alike. For runners who have been waiting for a stability shoe that does not feel firm and joyless, this is the one worth hunting down.
