Merrell MTL Long Sky 2 Matryx

Merrell MTL Long Sky 2 Matryx review: what runners say

Fit

Precise fit, foot-hugging through the midfoot with a Matryx upper that holds its shape over time. Toe box slightly roomier than the Agility Peak 5; heel structurally problematic across multiple Merrell models.

Feel

Dual-density FloatPro midsole in a medium-firm setup: solid protection, ground feel present, no excessive softness. Responsive shoe designed to keep the terrain underfoot.

Durability

Matryx upper in high-tenacity Kevlar/polyamide: tear and abrasion resistance superior to standard mesh. Vibram Megagrip 5 mm lugs: expected durability high. Exact mileage figures not disclosed by sources.

Best for

Technical trail and Skyrunning up to shorter ultras (40–80 km); sweet spot between half marathon and marathon on mixed terrain. Performance-oriented light-to-medium-weight runners focused on ground feel.

Weak points

Insufficient heel fit: collar with minimal padding, slight play around the Achilles, blister risk in early runs. Recurring pattern across the full Merrell line confirmed by multiple sources.
