Saucony Endorphin Pro 4

A versatile carbon racer that excels at 5K and marathon distances but feels less natural at half-marathon pace, best suited for higher-volume feet seeking a stable, durable platform over outright speed.

Doctors of Running Youtube

A super shoe that shines at the 5K end and the marathon end of the spectrum, but struggles at half-marathon pace — both reviewers ultimately agreed it suits fast 5K running and steady marathon efforts.

Best for: 5K racing at fast paces or marathon racing at steady effort; not ideal for half-marathon / tempo paces in between

+5 earlier reviews from Doctors of Running

A durable, stable-neutral super shoe that is excellent at 5K pace and marathon effort but feels awkward at the half-marathon/tempo paces in between; the slightly softer, heavier evolution of the Pro 3.

Best for: Stable-neutral runners wanting a durable super shoe for 5K fast efforts or steady marathon pacing; forefoot strikers especially benefit from the stiff forefoot

100 miles tested · source

A more versatile and stable update that handles marathon to easy paces better than the Pro 3, though it loses some of the Pro 3's pop for very fast efforts.

Best for: True marathon racing and longer distances at easier efforts

35 miles tested · source

A comfortable but firmer-feeling super shoe with more versatility into faster paces than the SC Elite v4; works well for a runner who wants to push marathon pace with mild stability support.

Best for: Marathon to half marathon racing, particularly for runners needing a touch of guidance from sidewalls

A polarizing update where the same shoe can feel like a short-course speedster or a marathon cruiser depending on the runner's landing pattern, toe/MTP geometry, and pace needs — both testers like it for different reasons.

Best for: Depends heavily on runner mechanics — Andrea (midfoot lander) loves it for fast short races, Matt (heel striker) prefers it for marathon pace; likely better for higher-volume feet

A comfortable, stable-neutral super racer best for longer race distances, favored for its softer ride and accommodating upper even though it lacks outright top-end snap.

Best for: Runners wanting a stable-neutral super racer for marathon and half-marathon distances with a softer, more comfortable ride.

EDDBUD Youtube

A more consistent, stabilized marathon racer than the Adios Pro 4 — not better or worse, just more appropriate for runners who need stability or find the Adios too soft.

Best for: Runners wanting a more stabilized marathon racer without aggressive medial cutouts

+5 earlier reviews from EDDBUD

A plush, durable marathon racer that can also serve as a training shoe — wider fit and durable foam make it the best rotation option of the four.

Best for: Marathon racing and high-mileage training for runners with slightly wider feet

A versatile half/marathon banger with improved responsiveness, strong durability, and a slightly cheaper price than the Alphafly 3 — traditionalists may prefer it, though EDDBUD narrowly picks the Nike overall.

Best for: Half and full marathon racing for traditionalists who prefer a standard carbon-plate feel over the Alphafly's air pods

EDDBUD's pick of the super-shoe pack — edges out the competition with top versatility across 5K to marathon, better upper than Vaporfly 3, and improved outsole durability.

Best for: All-around carbon super-shoe racer from 5K to marathon, especially for higher-volume feet

EDDBUD's pick of the four — lighter, more propulsive, cheaper (£230 vs £285), and newly versatile across all race distances thanks to the extra foam layer and improved outsole.

Best for: Versatile racing from 5K up to the marathon, especially for lighter runners.

A top-tier race and training super shoe — more versatile than the Pro 3 with improved outsole durability, excellent build quality, and a redesign that makes the Pro 4 usable across any race pace.

Best for: Top-tier race and fast-training super shoe for 5K to marathon

FORDY RUNS Youtube

Fordy's best-value marathon pick around 120 pounds; versatile, competent, reliable with no issues across his marathons.

Best for: Budget-conscious marathoners wanting a plated race shoe

K
Kofuzi Youtube

A smooth and approachable carbon racer that Kofuzi will still recommend widely, though he personally prefers the Pro 3's extra pop — the HG top layer mutes the beaded PEBA bounce he was hoping would shine through.

Best for: Runners wanting an approachable carbon plated racer that is smoother and more cushioned than the Pro 3

SJ
Seth James DeMoor Youtube

A great value carbon-plated racer at $225 with solid breathability and a dual-density midsole — performs well but doesn't feel as bouncy as some alternatives.

Best for: Best value carbon marathon and half marathon racer, also works as up-tempo training shoe

TR
The Run Testers Youtube

A marathon-oriented carbon racer that the reviewer prefers to save for longer distances rather than 10k racing.

+1 earlier review from The Run Testers

The more accessible and versatile of Saucony's carbon racers — a snappy but safe bet with reliable cushioning and stability that will work for most runners, especially those on tired legs or racing twisty courses.

Best for: Marathon racing and marathon-pace training for a wide range of runners including beginners; runners who want a versatile racer they can also train in
