The Saucony Endorphin Speed 5 and the Saucony Endorphin Azura are two siblings of the Endorphin family: same PWRRUN PB foam, same 8 mm drop, same SPEEDROLL geometry that tips the stride forward. Their difference comes down to one word: the plate.
On the scale, the two are within a few grams of each other. The Azura takes the height advantage with a 40 / 32 mm stack, versus 36 / 28 mm for the Speed 5, which sits closer to the ground.
The Speed 5 owes its reputation to its semi-rigid nylon plate, reworked on this version for more flexibility: it delivers real propulsion, more approachable than a carbon plate.
The Azura makes the opposite bet: no plate at all, the full height in PWRRUN PB, and a rocker that does the work. The ride stays lively, even without a pronounced bounce, in a less rigid stride, with a slightly firmer character at impact.
In use, the Speed 5 remains the most versatile of the two: easy runs, workouts, and above all racing from 10K to the marathon, where its plate makes the difference on race day. The Azura shines in training: tempos, intervals and brisk long runs, with good stability despite its height, thanks to its fairly wide base.
Both technical mesh uppers are very breathable, in keeping with the rest of the Endorphin line, and both fit true to size, slightly snugger in the forefoot for the Azura.
Budget can decide: the Azura costs about $25 less, a real selling point.
Endorphin Speed 5 or Endorphin Azura: which should you choose?
If you are looking for one shoe to train and race in, the Speed 5 (9.5/10) remains the benchmark: its nylon plate makes it the lineup’s ultimate all-rounder.
The Azura (9.2/10) is the smart pick for training: cheaper, nearly as responsive and taller underfoot, it is perfect if you race in another pair, or if you prefer running without a plate.
