Salomon S/Lab Phantasm 2 Review: 9mm, $275, Unisex Racer

Disclosure: TrainingPlan has not hands-on tested this exact model. This research-based review uses Salomon exact-model and ASF technical materials plus independent exact-generation testing. No Amazon US listing is currently verified for publication.

Quick Verdict

The original Salomon S/Lab Phantasm 2 is a unisex road racing shoe with PEBA-based foam, a full-length carbon-fiber Energy Blade, a lightweight mesh upper, and Contagrip rubber. Salomon specifies 37.5mm at the heel and 28.5mm at the forefoot for a comparatively high 9mm drop. It is a true super shoe, but not the lighter, revised ASF upper variant or the non-S/Lab Phantasm 2 trainer.

The published reference is 219g, about 7.7 ounces, in unisex sizing. Independent samples have weighed as little as 7.4 ounces. The original arrived October 1, 2023 with a MSRP: $275 US MSRP and was later replaced in parts of Europe by the ASF version.

Key Specifications

Salomon's exact product URL preserves the original identity, while the brand's ASF technical story confirms the shared platform's 219g reference, 9mm drop, 37.5/28.5mm stack, PEBA foam, and carbon plate. Believe in the Run's launch review provides the October date, MSRP: $275 price, and 7.4-ounce men's US 9 sample.

What Changed

The old record listed a 6mm drop, 35/29mm stack, 6.9/5.9-ounce gendered weights, MSRP: $250 price, and Energy Surge foam. Those values did not match the original S/Lab Phantasm 2. The correction uses 9mm, 37.5/28.5mm, the shared 7.7-ounce unisex reference, MSRP: $275 launch MSRP, and PEBA-based foam.

The database repeats the unisex reference in both required weight fields rather than pretending a women-specific sample exists. The article also distinguishes the S/Lab racer from the non-S/Lab Phantasm 2 performance trainer and the later ASF construction. The former Amazon link was removed because those similarly named products create a high substitution risk.

Ride and Intended Use

The PEBA-based midsole sits above and below a spoon-shaped carbon Energy Blade. The combination creates rebound, longitudinal stiffness, and a fast transition when loaded at speed. Contagrip provides more rubber traction than many road super shoes, which independent testers repeatedly identified as a strength.

WearTesters' performance review used the shoe for speed work and shorter races and found the ride soft, bouncy, and rapid. It can serve 10K through marathon racing for runners who engage the geometry, but the model name does not guarantee comfort at any distance.

Fit and Sizing

The most consistent limitation is length. Believe in the Run and WearTesters both found the shoe at least a half size long for many feet. The upper is lightweight and not highly stretchy, while the heel and midfoot platform are relatively narrow.

Some runners may size down; others may keep normal size to accommodate swelling. Neither rule is universal. Try the exact original with race socks and verify heel hold, arch contact, toe clearance, and plate alignment. The shoe-selection guide explains those checks.

What Works Well

The shoe provides genuine PEBA response and full carbon stiffness at a competitive 7.7-ounce reference. Its 9mm drop is unusual among current racers and may suit runners who prefer more heel elevation. Contagrip offers reliable paved-road traction, including in less-than-perfect conditions.

The original is also mechanically distinct from Salomon's earlier composite-fiber racing attempts. That makes it a legitimate entrant in the carbon-racing guide, not simply a trail brand experiment.

Tradeoffs

At MSRP: $275, the launch price exceeded many established competitors. Doctors of Running's review found the long fit, narrow heel/midfoot, and neutral high platform unstable for some mechanics. Those limitations matter more over fatigue.

The lightweight upper and race foam are not built for carefree daily use. Avoid fixed lifespan claims; inspect outsole wear, foam creasing, upper stress, and plate-area separation. The replacement guide provides condition-based checks.

Who Should Consider This Shoe

Consider it if you want a high-drop, PEBA-and-carbon racer with strong road traction and the long unisex fit aligns with your foot. It can suit faster workouts and races when the narrow platform feels controlled.

Who Should Look Elsewhere

Look elsewhere for wide sizing, a stable broad heel, flexible daily training, conventional sizing, or better value. The shoe-selection guide is more useful than buying based on S/Lab branding.

Cross-Brand Comparison

The Adidas Adizero Adios Pro 3 uses ENERGYRODS and a broader marathon-oriented geometry at a lower launch price. The Puma Fast-R NITRO Elite 3 is much lighter but costs MSRP: $300. Phantasm's distinguishing traits are 9mm drop and Contagrip.

Same-Brand Comparison

The Salomon Aero Glide 2 is an unplated road trainer with a completely different role. The S/Lab Ultra 3 is an older trail racer. Only S/Lab Phantasm 2 is the PEBA/carbon road super shoe discussed here.

Value

The MSRP: $275 MSRP was difficult to justify against mature MSRP: $225–MSRP: $250 rivals. A substantial old-stock discount can improve value, but exact original identity, foam storage, unusual sizing, and return terms remain essential.

Final Verdict

The corrected S/Lab Phantasm 2 is a unisex 7.7-ounce, 9mm-drop road racer with 37.5/28.5mm stack, PEBA-based foam, a full carbon Energy Blade, and Contagrip. It offers credible speed and traction, balanced by long fit, a narrow neutral platform, and premium launch pricing.
