A cushioned carbon racer with a bouncy PEBA midsole that shines at marathon pace, though the overcomplicated aerodynamic upper frustrates most testers and the wide forefoot geometry favors heel strikers over forefoot runners.

BI
Believe in the Run Youtube

A meaningful step forward for Salomon on the racing side — the OptiVibe Plus midsole is great and the carbon plate is propulsive — but the aerodynamic upper is overcomplicated and the wide forefoot geometry favors heel/midfoot strikers, making it a tough sell at $280 against established super-shoes.

Best for: Heel to midfoot strikers who want a soft, bouncy PEBA racer and aren't put off by a fiddly aerodynamic upper.

Ran 20 miles at sub-7 pace in 2:12 and finished in good shape — the midsole is smooth, controlled, and efficient, but the aerodynamic upper is a gimmick most runners don't need and Kieran wouldn't pick this over the Puma Fast-R 3 or Asics Metaspeed Edge Tokyo.

Best for: Forefoot/midfoot strikers chasing fast paces who don't mind a fiddly aerodynamic upper.

An excellent carbon-plate racing shoe with a fantastic, comfortable, bouncy PEBA midsole that's let down by an over-complicated aero gaiter upper and stiff competition; a top-half carbon racer but not quite a top-pick over the Metaspeed Ray, Metaspeed Sky Tokyo, or Puma Fast-R 3.

Best for: Marathon racing for runners who want a more cushioned, comfortable carbon racer with PEBA squish — provided they can tolerate the fiddly aero upper.

First-run verdict is that this is the best carbon-plate shoe Salomon has made — lightweight, bouncy, more competitively priced than predecessors, with a comfortable PEBA ride that didn't blow Nick away but should hold up well over long distances. Skip the aerodynamics talk; the underfoot feel is the real story.

Best for: Long-distance road racing, especially marathons; runners who want a comfortable, cushioned PEBA carbon racer at 6.5 oz.

Frequently asked questions

Is the Salomon S/Lab Phantasm 3 good for long runs?

A cushioned carbon racer with a bouncy PEBA midsole that shines at marathon pace, though the overcomplicated aerodynamic upper frustrates most testers and the wide forefoot geometry favors heel strikers over forefoot runners.

How does the Salomon S/Lab Phantasm 3 fit?

Reviewers note: Salomon shoes run narrow and snug on him at his regular UK 8.5 — race fit is very secure and dialed in, but he'd consider half a size up for more room. The aerodynamic upper makes the shoe a 'ball ache' to get on; laces are fiddly. Once on, the gaiter creates a sock-like fit and the forefoot mesh feels airy.
