Quick Verdict

The Saucony Endorphin Pro 4 is a superseded carbon-plated racer released in March 2024. Saucony specifies 7.5 ounces for men, 6.5 ounces for women, 39.5mm heel stack, 31.5mm forefoot stack, and an 8mm drop. These figures replace the old 7.0/6.0-ounce and rounded 40/32mm record.

PWRRUN HG and PWRRUN PB foams, a full carbon plate, SPEEDROLL geometry, and an SRS sockliner produce a smoother, more accommodating race feel than many rigid super shoes. It remains a MSRP: $225 specialist built for faster running, not an automatic daily trainer or a performance guarantee.

Key Specifications

What Changed

Saucony's exact men's and women's pages provide the decisive weights, stack, drop, foam, plate, and race positioning. The old numbers were not harmless rounding: both weights were half an ounce low, while both stack values were half a millimeter high. The database and article now use the brand pair exactly.

The construction description also changes from “PWRRUN PB foam” to the documented dual-foam system. A layer of PWRRUN HG works with PWRRUN PB, the carbon plate, and SPEEDROLL. Saucony's launch communication confirms the MSRP: $225 price, although its adjacent Speed 4 specifications should not be misread as Pro 4 values.

Ride and Intended Use

Independent reviews describe Pro 4 as smoother and more stable than several aggressive racers. The dual foam and SRS sockliner soften the first contact, while the plate and rocker guide turnover. It works best from threshold and marathon-pace sessions through road races, especially for runners who find narrow, sharply tipped racers uncomfortable.

At recovery pace, the plate and rocker can feel excessive. Preserve the racer for purposeful sessions and use choosing running shoes to select a comfortable daily companion rather than treating carbon as universally beneficial.

Fit and Sizing

Saucony offered separate men's and women's references in standard width. Reviews commonly describe a more accommodating upper than minimal super shoes, but it remains a secure race fit. Check toe length, lateral pressure, heel hold, and tongue placement at running pace.

Runners needing more flexibility can compare the nylon-plated Saucony Endorphin Speed 4. Do not add length solely to create width; movement inside a race shoe can undermine control.

What Works Well

Pro 4's strongest trait is accessibility within the carbon-racer category. The 8mm geometry is conventional, the rocker transition is smooth, and the upper is less austere than some peers. The dual foam gives cushioning without relying on one extremely soft compound.

Its 39.5mm heel also fits just below the 40mm road-racing limit. The outsole has useful coverage for workouts, although low durability remains a conservative classification for a specialized racer rather than a predicted failure point.

Tradeoffs

At 7.5 ounces for men, Pro 4 is not category-leading in weight. Some runners will prefer a more aggressive rebound, while others may find the high plate stiffness tiring. MSRP: $225 is difficult to justify if it does not clearly outperform a familiar trainer in direct testing.

Watch foam response, plate sensation, grip, and upper hold instead of following a fixed super-shoe mileage rule. When to replace running shoes explains the relevant signals.

Who Should Consider This Shoe

Consider it if you want a smoother, relatively stable carbon racer for 10K through marathon efforts and prefer an 8mm drop. It is particularly plausible for runners who find the narrowest elite shoes too demanding.

Who Should Look Elsewhere

Look elsewhere for wide sizing, a low platform, flexibility, or low cost. The Brooks Hyperion Elite 4 is firmer and more controlled, while the ASICS Metaspeed Edge Tokyo is lighter and cadence-specific.

Cross-Brand Comparison

The Nike Vaporfly 3 emphasizes low mass and a softer ZoomX sensation. Pro 4 feels more substantial and can be more stable. The best choice depends on fit, pace, and individual economy, not reputation.

Same-Brand Comparison

The Saucony Endorphin Pro 5 is the current successor, while Speed 4 is the more practical workout shoe. Pro 4 only wins on value when old stock is discounted and its exact ride is preferred.

Value

At MSRP: $225 launch MSRP, Pro 4 was below some MSRP: $250 racers but still premium. Superseded inventory should be meaningfully cheaper than Pro 5. The linked Amazon ASIN and exact title were verified on August 25, 2026; confirm version, size, seller, and returns at checkout.

Final Verdict

Saucony Endorphin Pro 4 is accurately a 7.5/6.5-ounce carbon racer with 39.5/31.5mm geometry, 8mm drop, and dual PWRRUN HG/PWRRUN PB cushioning. It is slightly heavier and lower than the old record but better researched: a smooth, relatively accommodating race tool with premium cost and specialized use.
