The Saucony Endorphin Speed 5 is here, and with it comes the big question: Is this still one of the best options for the everyday runner? In this review, we’ll break down what’s new, how it compares to version 4, how it performs, and whether it's worth the £180 price tag.
What’s New?
While Saucony didn’t overhaul the Speed 5, it brings some thoughtful refinements:
Midsole: PowerRun PB remains, paired with SpeedRoll technology and an 8mm drop (36mm heel, 28mm forefoot).
Weight: UK 9.5 weighs in at 258g – almost identical to version 4.
Plate: A tweaked nylon plate that no longer wings out on the lateral side, offering a slightly more stable feel.
Upper: Redesigned with a snug yet comfortable fit. The width, particularly in the heel, adds to the sense of stability.
Outsole: XT-900 rubber remains, but there’s new cutout design and improved rubber placement for durability.
In terms of fit, it’s got that familiar feel for those who’ve used previous Speed models – comfortable, true to size, and easy to lace down for a secure lockdown.
Performance & Ride
The ride of the Endorphin Speed 5 is the highlight here. It’s smooth, responsive, and – most importantly – versatile. It strikes a great balance between softness and firmness. The nylon plate adds spring without the overly stiff feel of carbon-plated shoes, making this a more forgiving choice.
The heel has been slightly widened, offering more inherent stability, especially noticeable on longer runs or for runners who may need just a little extra support without going into full “stability shoe” territory.
Compared to the Speed 4, this version feels a little more springy off the toe and marginally more rigid, in a good way. It delivers a consistent and reliable experience across different paces – from easy runs to tempo workouts.
Versatility is the Key
One of the Speed’s strongest assets has always been how much it can do. Whether you’re doing intervals, long runs, or even race day efforts, it performs across the board. It's the kind of shoe you can train in all week and then race in at the weekend — ideal for runners who want to keep their rotation minimal.
Compared to other super trainers:
Adidas Boston 13 is better for marathon-paced long runs.
Nike Zoom Fly 6 has more of a race-day bias.
Endorphin Speed 5 lands perfectly in between — a true jack of all trades.
Likes & Dislikes
Likes:
Redesigned upper is comfortable and secure.
Slightly wider platform improves stability.
Lightweight feel enhances performance.
SpeedRoll tech and PB foam still work brilliantly together.
Colourways (especially the “Mutant” version) look great.
Above all: unmatched versatility.
Dislike:
At £180 RRP, it’s on the pricier side — especially if you can’t find a discount code.
