Merrell MTL Long Sky 2 Matryx Review: Correct Model, 4mm Drop

Disclosure: TrainingPlan has not hands-on tested this exact model. This research-based review uses Merrell's men's and women's exact-model pages plus independent exact-model reviews. No Amazon US listing is currently verified for publication.

Quick Verdict

The Merrell MTL Long Sky 2 Matryx is a light technical-trail racer built around a single-layer, Kevlar-reinforced woven upper, FloatPro midsole, ETPU footbed, and 5mm Vibram Megagrip lugs. At 23.5mm in the heel and 19.5mm in the forefoot, it stays relatively close to the terrain while the low-stretch upper emphasizes secure placement.

Merrell lists 8.29 ounces for men and 6.88 ounces for women, rounded in the catalog to 8.3 and 6.9 ounces. The 4mm drop, rather than the old record's 8mm, follows directly from the exact-model geometry. Launch coverage in April 2024 listed MSRP: $160; the currently sold 45th-anniversary version is MSRP: $170.

Key Specifications

Merrell's men's product page supplies the exact name, weight, geometry, construction, and rugged-trail positioning. The women's page supplies the 6.88-ounce reference. Believe in the Run's launch review establishes April 2024 availability and MSRP: $160 launch pricing.

What Changed

The old entry called the shoe “MTL Long Sky 2” but described a Matryx upper. That conflated two selectable products on Merrell's site: the original mesh/TPU shoe and the later Matryx update. The image and article intent match the Matryx version, so the audit corrected the visible model name while preserving the stable product ID and article route.

That identity repair changes several specs. The audited Matryx version is 4mm drop, 23.5/19.5mm stack, and 8.3/6.9 ounces—not 8mm, 26/18mm, and 8.3/7.0. The old Amazon destination was quarantined because an exact Matryx listing was not verified and the non-Matryx product is not an acceptable substitute.

Ride and Intended Use

The moderate stack and FloatPro foam create a direct trail ride rather than maximal isolation. The ETPU footbed adds a small resilient layer, while 5mm lugs and a low-stretch upper aim to keep the platform controlled during frequent changes in direction, elevation, and footing.

iRunFar's exact-model review positions the shoe for technical running and racing, with strong grip and a precise feel. That does not make it the best choice for every long race: protection preference, terrain sharpness, and fit determine whether a lower platform remains comfortable.

Fit and Sizing

Matryx resists stretch, so the initial shape matters more than it would in a soft knit upper. The bootie-like heel and midfoot are designed for lockdown, while the forefoot is not a broad anatomical platform. Believe in the Run's testers reported heel rubbing and fit sensitivity, including blister concerns for some feet.

Try it with trail socks and test a descent. Check heel contact, Achilles pressure, toe clearance, and forefoot width before assuming the light upper will loosen. The shoe-selection guide covers those checks.

What Works Well

The shoe is genuinely light for rugged trail, particularly the 6.9-ounce women's reference. Vibram Megagrip is paired with 5mm lugs, giving more penetration than a shallow road-to-trail pattern. The upper's aramid reinforcement supports precise lateral hold without needing thick overlays.

Those elements create a coherent race package: light, secure, and traction-focused. The trail-shoe guide explains why surface and lug geometry should be considered alongside weight.

Tradeoffs

The close upper can create heel or forefoot pressure, and the moderate stack transmits more sharp-rock sensation than a maximal model. Five-millimeter lugs are less pleasant on pavement and are not as widely spaced as a dedicated mud shoe. A specialist build also offers less everyday versatility than a conventional trail trainer.

No fixed durability mileage is justified. Inspect lug rounding, Matryx abrasion, outsole bonding, and a meaningful change in midsole feel. The replacement guide explains those condition-based signals.

Who Should Consider This Shoe

Consider it for technical trail racing, fast mountain runs, and runners who value low weight, secure hold, and strong wet/dry rubber more than plushness. It is especially compelling when the exact Matryx fit is comfortable.

Who Should Look Elsewhere

Look elsewhere for a roomy forefoot, maximal rock isolation, frequent pavement, deep sloppy mud, or a relaxed easy-day upper. The shoe-selection guide is useful before buying on weight alone.

Cross-Brand Comparison

The HOKA Torrent 3 is another lower, agile trail shoe but has a more conventional mesh build and shallower overall traction brief. The NNormal Kjerag 02 is a premium precise racer with different foam and outsole geometry.

Same-Brand Comparison

The Merrell MTL Skyfire 2 is an even more stripped-back short-course racing tool. The Merrell Agility Peak 5 adds cushioning and long-run protection. Long Sky 2 Matryx sits between them.

Value

The MSRP: $160 launch MSRP was reasonable for a Kevlar-reinforced upper and Vibram outsole. The MSRP: $170 anniversary version adds current availability, not a new geometry. Compare exact color/version, condition, and return terms rather than treating current and launch prices as a contradiction.

Final Verdict

The corrected MTL Long Sky 2 Matryx is an 8.3/6.9-ounce, 4mm-drop technical-trail racer with 23.5/19.5mm stack, FloatPro foam, and 5mm Vibram Megagrip lugs. Its light, precise build is the strength; close fit and moderate protection are the honest costs.
