The Grivet Take
The Endorphin Pro 4 is Saucony's marathon-distance race shoe, tuned softer and roomier than the Pro 3. PWRRUN PB cushion sits under a new PWRRUN HG topsole and a full-length carbon plate; the combination protects on long miles without going dead. Toe box, midfoot, and tongue all opened up versus the v3, so runners who found Saucony's old race shoes too snug should feel the difference. This is the marathon and half-marathon pick in a racing rotation, not a 5K-and-down shoe. Runners chasing maximum responsiveness and pop should consider the Nike Alphafly Next% 3 or the Adidas Adios Pro 4; runners who wanted a Saucony race shoe but the Pro 3 felt cramped should try the v4.

Support
Support TypeSupport Type describes how much built-in guidance the shoe has. Neutral shoes do not add support structure. Stability shoes use geometry, rails, firmer foam, or frame designs to create a more guided feel. Motion control shoes are the maximum-support category and are rare in modern running.

How it fits
Fits true to size for most runners, with half a size up showing up as a common adjustment for runners chasing extra toe-box room. Toe box runs noticeably wider than the Pro 3 and has more vertical volume. Midfoot is roomier overall, and the integrated knit tongue keeps lace pressure off the top of the foot. Heel hold is secure thanks to a silky liner and a new speed-lacing system that locks down without manual adjustment. Available in standard (D) only for men's. Customer reviews note the wider midfoot creates tongue creasing for narrow-footed runners.
How it feels
Cushion is high and leans soft. PWRRUN PB underneath the new PWRRUN HG top layer reads as bouncy with a pinch of firmness, which keeps the shoe from feeling like a marshmallow at race pace. The carbon plate is rigid through the forefoot, so the shoe drives through toe-off; ground feel is muted by the 40mm heel stack. Rocker geometry is less aggressive than the Pro 3, forgiving at slower paces but slightly less snappy when pace drops. Energy return is high; this is built for marathon and half-marathon distance, not a 5K shoe.

Tech, translated
PWRRUN PB is Saucony's PEBA-based race foam: light, bouncy, and built for distances where energy return matters most. New for the Pro 4 is PWRRUN HG, a topsole foam first used on the Endorphin Elite that adds compliance underfoot and softens the ride versus the Pro 3.
The carbon plate runs the length of the shoe and provides longitudinal stiffness, working with Saucony's SPEEDROLL geometry to roll the foot forward through toe-off. The combination keeps cadence high in late-race miles when leg fatigue would otherwise pull stride length down.
The knit upper is more pliable than the Pro 3's, with a built-in tongue that protects the top of the foot from lace pressure. The new speed-lacing system locks the heel down without manual adjustment, useful when fatigue makes mid-race adjustments awkward.
Frequently asked
Does the Saucony Endorphin Pro 4 run true to size?
The Pro 4 runs true to size for most runners, with half a size up showing up as a common adjustment for runners chasing extra toe-box room over marathon distance. The forefoot is noticeably wider than the Pro 3, so runners who sized up in the v3 may not need to in the v4. Available in standard (D) only for men's.
How does the Saucony Endorphin Pro 4 compare to the Endorphin Pro 3?
The Pro 4 is roomier through the midfoot and toe box, softer underfoot, and less aggressive at the forefoot rocker than the Pro 3. The carbon plate carries over unchanged, but the v4 adds a PWRRUN HG topsole that softens the ride. Pick the Pro 4 if the v3 felt cramped or you want more underfoot compliance; pick the Pro 3 if you valued the snappier forefoot rocker and snugger race fit.
Is the Saucony Endorphin Pro 4 firm or soft underfoot?
The Pro 4 leans soft, with the new PWRRUN HG topsole adding meaningful compliance underfoot versus the firmer Pro 3. The bounce remains thanks to PWRRUN PB underneath, and the carbon plate keeps the ride from feeling unstable. Runners who want a firmer race-day platform should look at the Pro 3 closeout instead.
What distance is the Endorphin Pro 4 built for?
The Pro 4 is tuned for marathon and half-marathon distances. The carbon plate, 40mm cushion stack, and softer PWRRUN HG topsole protect on long efforts where leg fatigue and underfoot compliance matter most. For 5K and 10K racing the firmer, snappier Pro 3 or a different super shoe will feel better; for shorter speed work the Endorphin Speed 4 is the family training partner.
How long does a pair of Endorphin Pro 4 last?
Race-day shoes are tuned for performance over longevity. Most runners get 200 to 300 miles of race-quality performance from PEBA-based super shoes before the foam compresses and the responsive feel fades. The Pro 4 is no exception. Save the shoe for race-day and key marathon-pace workouts; daily mileage in race shoes burns through their useful life quickly without delivering the daily-training benefit.
