■ Caution
IncrediRUN is extremely soft. If you like a firm, connected racer this will feel vague underfoot.
Straight answers
- Is the Saucony Endorphin Elite 3 legal for road racing?
- Yes. The Saucony Endorphin Elite 3 measures 39.5mm at its highest point, 0.5mm inside the World Athletics 40mm road limit. The limit only binds Applicable Competitions; most club and local races apply no shoe rule at all.
- How much does the Saucony Endorphin Elite 3 weigh?
- 204g in a men's US 9 (UK 8), by the manufacturer's stated figure. Weight moves roughly 3.5% per UK size step, so a UK 11 weighs materially more than the spec sheet says.
- What is the stack height and drop of the Saucony Endorphin Elite 3?
- 39.5mm at the heel and 31.5mm at the forefoot — a 8mm drop. A carbon-fibre plate runs through IncrediRUN (twin layer).
- How long does the Saucony Endorphin Elite 3 last?
- We estimate roughly 240km of competitive life — the point at which the foam has degraded enough that you are no longer getting the benefit you paid £300 for, not the point at which the shoe falls apart. Spread over race cycles, that is what the cost-per-race figure on this page is built from.
- Is the Saucony Endorphin Elite 3 good for a marathon?
- Yes — the marathon is one of the distances it is built for (10k, half marathon and marathon). The softest ride at this level by some distance, and the third generation finally made it serious rather than just fun. A genuine top-tier option.

Drawn from the manufacturer’s stated stack height, which is not the measurement World Athletics takes — the rule is measured on a men’s US 8.5 sample, and larger sizes may legally exceed it. An indication, not a ruling. Limits bind Applicable Competitions; most club and local races apply no shoe rule at all. What that means in practice.
