Salomon S/Lab Phantasm 2 vs Salomon S/Lab Phantasm 3:
Which to Choose
Verdict
Upgrade if your goals have grown past the 10K — the Phantasm 3 turns this line into a real carbon-plated, marathon-capable super-shoe, adding a plate, softer PEBA cushioning, more responsiveness, a lower 6mm drop, and lighter weight, all clear steps forward for race day. But don't treat it as a like-for-like replacement: if you specifically loved the Phantasm 2 as a firm, plateless, planted short-course tempo racer with strong ground feel, the 3's tall, tippy, plate-driven ride is a different animal, and keeping the 2 for fast-day duty makes sense. It comes down to whether you want a short-course sharpening tool (the 2) or an aggressive long-race weapon (the 3).

Who Should Choose Each Shoe
Choose
Salomon S/Lab Phantasm 2
Choose the Phantasm 2 if what you actually want is a firm, low-profile tempo trainer and short-course racer — a shoe for 5K and 10K PBs, tempo repeats, and speed sharpening where you value ground feel, a quick, direct rollover, and a committed forefoot stride. It's also the better pick if you want a more planted, less tippy platform that still behaves at slower paces, or if you simply don't want a carbon plate dictating your stride. Experienced runners who liked the honest, unplated feel of this line and never needed marathon range will find little reason to move on.
Choose
Salomon S/Lab Phantasm 3
Choose the Phantasm 3 if you're an experienced, fast runner chasing personal bests from 10K up to the marathon and you want a dedicated, aggressive race-day tool. The PEBA-and-carbon combination gives you the propulsive toe-off and long-distance protection the plateless Phantasm 2 simply can't match, and the added cushioning and lower drop make it far more comfortable for sustained half and full marathon efforts. It rewards runners who are comfortable committing to fast, purposeful running on a tall, narrow platform — not those who want an easy-paced or do-everything shoe.
Head-to-Head
The single biggest change is under your foot: the Phantasm 2 has no plate and rides on Salomon's firm, lively Energy Surge foam, delivering plenty of ground feel and direct, quick transitions. The Phantasm 3 replaces that entirely with supercritical PEBA "optiFOAM+" over a full-length, spoon-shaped "energyBLADE" carbon plate — a true super-shoe drivetrain that snaps you through toe-off once you're rolling. That shows up in the metrics: cushioning rises from moderate to high, and responsiveness jumps from good to very high. The drop also drops, from 8mm on the 2 to 6mm on the 3, and the 3 is the lighter shoe despite carrying more foam and taller stack, so you get a more cushioned, more propulsive ride without a weight penalty. The trade-off is stability and versatility: the Phantasm 2's lower, plateless platform is the more planted, more forgiving ride and stays usable even when you ease off the pace, whereas the 3's tall, narrow racing geometry can feel tippy and unsettled at easy jog pace and only comes alive at committed race effort. Their sweet spots have shifted accordingly — the 2 peaks at hard 10K and tempo repeats and tops out around the half, while the 3 extends the range upward, with the half-to-marathon window as its home and a faster optimal pace band. In short, this isn't an iterative refresh; the 3 is a recategorization from firm short-course tempo racer to plated marathon-capable race shoe.
