What Saucony claims

According to the 3 November 2026 press release, the Endorphin Speed 6 introduces a new PWRRUN PBX midsole, a PEBA-based "superfoam" with a beaded structure, a redesigned nylon plate and a "refined" SpeedRoll geometry, with 2 mm more foam underfoot. Chief Product Officer Brian Moore describes it as "lighter and even more cushioned". The stated purpose is fast training, hard sessions and racing, completing the Endorphin family (Elite 3, Pro 5, Speed 6, Azura).1 These are all the manufacturer's words: "more responsive", "more propulsive" and "smoother roll" are not claims a press release can verify.

What testers measured

Doctors of Running publishes measurements from its own pair: 232 g in a men's US 9 (203 g in a women's US 8), a 38 mm heel and 30 mm forefoot stack, and an 8 mm drop.5 These are an independent editorial team's measurements on one specific pair: a useful reference, not a factory specification verified by us. Road Trail Run also reports a wider midfoot and heel platform than the previous version.6

What independent reviews say

Three outlets ran in the shoe before the Italian launch. Runner's World (15 October 2026) calls it the "snappier than ever" Speed thanks to the new foam and a more tilted rocker, with a more compliant nylon plate than before; it also flags hot spots reported by testers.4 Doctors of Running (25 September 2026) praises the responsive foam, snappy forefoot and smooth transitions, with three reservations: outsole durability doubts, initial stiffness and a tapered toe box.5 Road Trail Run (14 September 2026, four testers) calls it a "return to form" for the series after the less convincing versions 4 and 5.6 None of these tests are ours: we report other people's verdicts with their dates.

Price and availability

On the Italian saucony.com page, read 4 November 2026, the Endorphin Speed 6 sells for €200.2 On the US page, same reading, it is $180 and in stock in four colorways (White/Citron, Black/White, Surf/Black, White/Naval) with most sizes available.3 The press release also mentions "select retailers" without naming them.1

What is only claimed

Coming from Saucony with no independent confirmation read by us: the "greater energy return" of PWRRUN PBX, the propulsion "boost" attributed to the new plate, the SpeedRoll improvement and the "fast training to racing" positioning.12 The cited reviews are consistent with a snappier shoe than the previous version, but they remain the experiences of a few testers on a few pairs, not laboratory measurements.

Limits

  • WOLFLAB has not tested the shoe: every usage verdict cited belongs to the linked outlets, with publication dates.
  • Weight and stack heights are Doctors of Running measurements on one pair, not official specifications verified by us.5
  • Prices and availability read on 4 November 2026: they can change; availability at other Italian retailers was not verified.
