In this comparison, I break down the key specs, share what I like about each, and wrap up with my final thoughts on which type of running and runner each shoe suits best.

Both the Merrell MTL Long Sky 2 Matryx and The North Face VECTIV Sky 2 were designed with fast, technical trail running in mind.

What’s Good

Merrell MTL Long Sky 2 Matryx

  • Secure, Agile Fit: The innovative Matryx upper (a blend of Kevlar and high-tenacity polyamide) keeps your feet locked in place for quick changes in direction – it’s also supportive, breathable and incredibly durable.
  • Responsive Ride: The dual-density FloatPro™ Foam offers a balanced ride that’s responsive on steep climbs and technical descents, and fast on the flats without the need for a carbon plate.
  • Reliable Traction: The Vibram Megagrip outsole, with its aggressive 5mm lugs, grips confidently on rugged surfaces – it’s unbeatable right now.

The North Face VECTIV Sky 2

  • Lightweight and Quick: Weighing in at just 8.4 oz, this shoe feels light and nimble. The full-length carbon-fiber plate helps with forward propulsion on rolling terrain but in my opinion plates are never great when it comes to navigating technical terrain – however these performed admirably.
  • Firm, Race-Tuned Response: Its nitrogen-infused TPU foam, combined with the carbon plate, delivers a firm ride that’s built for speed on technical trails.
  • Strong Grip: The SURFACE CTRL™ outsole with 5mm lugs provides consistent traction whether the trail is dry, muddy, or rocky.

What’s Not So Good

  • Minor Heel Slip: There can be a slight heel slip initially. It usually settles after a few kilometers, but it might be distracting for some.
  • Firm Midsole: If you prefer extra cushioning on long, flat sections, the firm midsole might not offer the plush ride you’re looking for.

  • High Collar Feel: The higher ankle collar might feel intrusive, especially for those with lower ankle bones or if you prefer a lower-cut shoe.
  • Stiff Ride for Some: The firm setup, thanks to the carbon plate, is great for racing but might take some getting used to if you favor a softer ride over longer distances.

Final verdict

Merrell MTL Long Sky 2 Matryx is best suited for runners who thrive on dynamic, high-intensity trail runs with plenty of changes in direction and steep climbs. It’s a strong pick for skyrunners or anyone looking for a secure, agile shoe on rugged terrain.

The North Face VECTIV Sky 2 is a better match for runners who need a lightweight, responsive shoe for race-day efforts and technical sections. If you’re focused on speed and can handle a firmer ride, that will give a fast output (better for less technical racing), this shoe is a solid option.
