Our verdict
Firm, stable, and quick once you push.
The Endorphin Azura is a plate-free performance trainer with a firm PEBA foam, a broad platform and a pronounced forefoot rocker that rewards steady and uptempo running. It suits neutral runners who like a firm, guided ride for long runs and tempo days, and testers split on how pleasant it is at slow, easy paces.
Strong points
- Comes alive at tempo and marathon pace, with no plate needed
- Unusually stable for a neutral shoe, thanks to a wide, firm base
- High energy return in RunRepeat’s lab: 70.6% heel, 74.7% forefoot
- True to size for nearly every tester
- Light for its stack: about 240 g in a men’s US 9
Weak points
- Firm underfoot: 40.2 AC, harder than RunRepeat’s 35.5 AC average
- Can feel harsh or long-striding at slow, easy paces
- Tapered forefoot crowded or rubbed some testers’ toes
- Thin 2.3 mm outsole, and durability reports are mixed
- No wide version
Who it fits
- You want one shoe for steady miles and tempo
- You like a firm, guided ride
- You land on your heel
- You run long
Who should skip it
- You want soft, plush cushioning
- Your easy days are very slow
- Your forefoot is broad

How it feels
Written from 8 published tests. We quote measurements, not impressions we did not have.
Plenty of foam, firmly tuned. A tall PWRRUN PB midsole with no plate, measured firm at 40.2 AC by RunRepeat, yet protective enough for long runs.
Neutral on paper, guided in practice. Sold as neutral, but a wide, firm base and sidewalls make it one of the steadier plate-free trainers, per Doctors of Running and RunRepeat.
A rocker that wants pace. High measured energy return and a sharp SpeedRoll rocker give a snappy toe-off at pace, but the rocker can feel stiff when jogging.
Plenty of foam, firmly tuned. The midsole is PWRRUN PB, Saucony’s beaded PEBA foam, with no plate. Doctors of Running list 40 mm at the heel and 32 mm at the forefoot; RunRepeat measured 40.7 and 32.7 mm. On the listed 40 mm heel, 58 of the 207 neutral road shoes in our catalogue have a taller one.
The feel is firmer than that stack suggests. RunRepeat measured 40.2 on the AC scale against a 35.5 average. RTINGS still rates the cushioning highly over long runs, and Runner’s Lab found impact absorption strong enough for a marathon.
Neutral on paper, guided in practice. Saucony files the Azura as neutral, but Doctors of Running found real guidance from the wide, firm platform, the sidewalls and the flared sole. RunRepeat measured a forefoot of 123.4 mm and a heel of 91.6 mm across, and calls the platform very stable.
Believe in the Run’s heaviest tester saw no medial wear on the midsole, which he usually gets in neutral shoes. RTINGS is a little more reserved: it rates stability 7.4 out of 10 and notes a narrower arch that gives less support at midstance.
A rocker that wants pace. RunRepeat measured 70.6 percent energy return at the heel and 74.7 at the forefoot, and RTINGS scores energy return 8.2 out of 10. The SpeedRoll rocker and toe spring do the rest: testers at Fleet Feet and Believe in the Run describe a snappy roll into toe-off.
That geometry is also its limit at slow speeds. Doctors of Running and Marathons.com found the stride long and the rocker stiff when jogging, and one Doctors of Running tester, a physical therapist, found the forefoot shape made her feel she was tipping off the front.

What the tests say
Published reviews agree the Azura is a firm, stable, plate-free trainer that feels best at steady to fast paces and fits true to size. They part ways on easy runs, toe room and how long the thin outsole lasts.

Upper. A thin, lightly stretchy two-layer mesh with structural overlays, per Doctors of Running and Runner’s Lab. RunRepeat rates breathability 4 out of 5, and both Marathons.com testers found it very well ventilated, though one wanted a softer, more comfortable feel.
Tongue. Thin and gusseted, with padding only where the laces press. RunRepeat measured 4.3 mm and counts four foam pads.
Heel. A small, stiff counter with a flexible overlay and little padding; one Doctors of Running tester wanted more behind the Achilles. RunRepeat rates the counter 3 out of 5 for stiffness and finds no pull tab.
Midsole. Beaded PEBA foam, with no plate or stiffening rods, shaped into Saucony’s SpeedRoll rocker. RunRepeat measured it at 40.2 AC, with flex at 16.6 N and torsional rigidity at 14.5 Nm, both close to its averages.
Insole. RunRepeat measured 4.4 mm. A Doctors of Running tester found a raised medial wall on the sockliner narrowed the rearfoot uncomfortably for her.
Outsole. XT-900 rubber with broad coverage and a lateral midfoot cutout, per Doctors of Running. It is thin, 2.3 mm in RunRepeat’s lab, and scored 0.51 for traction. Runner’s Lab found it reliable on wet asphalt, while a Doctors of Running tester slipped on wet, sandy roads.

Durability. Reports differ. RunRepeat measured just 0.5 mm of outsole wear and rates heel padding durability 5 out of 5 but the toe box 2 out of 5. A Marathons.com tester saw edge wear after 200 km and expects about 600 km in total; his colleague noticed wear after roughly 100 km. The Run Testers find the foam long-lasting but warn the thin rubber may go first.

Toe room
RunRepeat measured a 72.2 mm toe box and a height of 28.3 mm, and RTINGS gives toe box height full marks. The front still tapers: some testers had no issue, others felt crowded on long runs.

Full sizing notes from testers
RunRepeat’s readers, RTINGS, Fleet Feet, Runner’s Lab and The Run Testers all found it true to size, and Running Warehouse agrees. One Doctors of Running tester preferred a half size up, as she does in other Endorphin models.
Width is the open question. Running Warehouse finds the midfoot snug for wider feet, and testers at Believe in the Run and Fleet Feet found the forefoot taper crowded their toes. Lockdown is secure with no heel slip, per Doctors of Running and Marathons.com.
There is no wide version: Saucony lists a single medium width for men, and RTINGS and Fleet Feet confirm there is no 2E. RunRepeat also lists a narrow men’s version, which may not be sold in every country.

Questions runners ask
Is the Saucony Endorphin Azura true to size?
Yes for most runners. RunRepeat’s reader poll, RTINGS, Fleet Feet, Runner’s Lab and The Run Testers all report a true-to-size fit. The forefoot tapers, though: some Believe in the Run and Fleet Feet testers felt their toes crowded, and one Doctors of Running tester preferred a half size up, as in other Endorphin models.
Endorphin Azura or Endorphin Speed 5: which should I choose?
Choose the Endorphin Speed 5 if fast intervals and target splits matter most: it adds a nylon plate on a lower 36 mm heel, and RunRepeat prefers it for interval work. Choose the Endorphin Azura for a taller, plate-free shoe that Fleet Feet and The Run Testers find more comfortable on relaxed, longer miles.
Is the Endorphin Azura good for easy runs?
It depends how slow your easy runs are. The Run Testers find enough cushioning for easy runs of any length. Doctors of Running and Marathons.com testers found the Endorphin Azura firm, with a rocker that feels long and stiff when jogging. If your recovery days are very slow, a softer shoe may suit them better.
Can you race a marathon in the Endorphin Azura?
Yes, as a plate-free option. Running Warehouse testers name marathon pace as its sweet spot and RTINGS scores it 7.9 out of 10 for half and full marathons. RTINGS also finds it heavy next to dedicated super shoes, so a plated racer remains the faster choice on race day for most runners.
Does the Endorphin Azura come in wide?
No. Saucony lists a single medium width for men, and RTINGS and Fleet Feet confirm there is no wide version. RunRepeat lists a narrow men’s version as well. With a forefoot some testers found tapered, runners with broad feet should try it on before committing.
Is the Endorphin Azura stable enough if my foot rolls in?
The Endorphin Azura is a neutral shoe, not a stability shoe, but reviewers find it unusually steady: Doctors of Running grade its stability A and describe guidance from its wide, firm platform and sidewalls. For a marked inward roll, a dedicated stability shoe is the safer choice. It guides the foot; it does not treat anything.
Is the Endorphin Azura good for walking?
Not really. Doctors of Running do not recommend it for walking or standing, and both Marathons.com testers found the pronounced forefoot rocker pushes you forward awkwardly at walking speed. A flatter, softer daily trainer will be more comfortable for long days on your feet.
