As a dedicated trail runner in Muskegon, Michigan, I was intrigued by the Merrell MTL Skyfire 2, touted as their latest elite trail running shoe. With impressive features like a BZM-8 rock plate for protection, dual density FloatPro Foam midsole for cushioning, Vibram MegaGrip outsole for traction, and breathable mesh and TPU upper for airflow, these shoes seemed perfect for my needs.
Upon lacing them up for the first time, I was impressed with the snug and secure fit, along with the optimal cushioning and support. On the trails, the shoes performed exceptionally well, with the rock plate shielding my feet from hazards, the midsole providing a comfortable and responsive ride, and the outsole delivering exceptional traction. The breathable mesh and TPU upper kept my feet cool and dry throughout my run.
Continuing to test the Merrell MTL Skyfire 2 on my regular routes, I found them to be lightweight and agile, maintaining my pace on ascents and descents. The plush cushioning remained supportive, even on longer runs, and the shoes held up well to the rough terrain without signs of wear and tear.
The Merrell MTL Skyfire 2 lived up to its promises of being the lightest and fastest elite trail running shoe, exceeding my expectations in comfort, traction, and durability. It quickly became my go-to choice for tackling the challenging trails and sand dunes, and I highly recommend it to fellow trail running enthusiasts who prioritize performance and reliability.
Merrell MTL Skyfire 2 Construction
The traction of the Merrell MTL Skyfire 2 was an absolute game-changer! The 5mm lugs on the Vibram MegaGrip outsole were like tiny claws that dug into the trail, providing a grip so reliable that I felt like I could conquer any terrain with ease. Whether it was wet or dry, muddy or sandy, these shoes had me covered. I took them through all sorts of challenging conditions during my testing, from slippery rocks to thick mud to rolling sand dunes, and they performed admirably in all of them, never once letting me down.

Vibram MegaGrip High Performance Rubber Outsole
One of the things that impressed me the most was how the lugs efficiently cleared out debris. No more worrying about rocks or twigs getting stuck in my shoe and slowing me down. These shoes were like a well-oiled machine, keeping my path clear and my stride smooth.
And let’s talk about the upper construction – it was a game-changer too! Made from breathable engineered mesh and TPU, it was like a fortress that kept sand and other pesky particles out of my shoe. I couldn’t believe how effective it was at keeping my feet clean and comfortable, even when I was plowing through sandy dunes. No more annoying sand getting in my shoes and causing discomfort or chafing. It was a breath of fresh air, literally!
With the Merrell MTL Skyfire 2, I felt like I had the ultimate trail running companion. The traction was out of this world, and the upper construction was a game-changer in keeping my feet clean and comfortable. These shoes are a force to be reckoned with, allowing me to tackle any trail condition with confidence and style. I was blown away by their performance, and they quickly became my go-to choice for all my trail running adventures.
Merrell MTL Skyfire 2 Fit
When it comes to fit, the Merrell MTL Skyfire 2 is definitely snug, giving you that locked-in feel. As someone with an average-width foot, the shoe fit me well overall, but I did notice that it was a bit narrow in the forefoot. There were times when my toes would graze against the tip of the shoe, and I couldn’t help but wonder if going up half a size would have provided a more comfortable fit, especially during longer runs when my feet tend to swell. However, I do acknowledge that some runners prefer a tighter fit for that added sense of stability, and it could simply be a matter of personal preference.

Heel Construction
But let me tell you, one aspect of the Merrell MTL Skyfire 2 that I absolutely loved was the ground feel. With a stack height of 25-19mm and a 6mm drop, these shoes gave me an unparalleled connection with the trail, allowing me to tackle uneven terrain with precision. The two-part, dual density FloatPro Foam midsole, combined with the innovative FlexPlate technology, provided stability and protection without adding unnecessary weight. The responsiveness and comfort of the midsole were evident during my runs, and I appreciated the perfect balance it struck between cushioning and ground feel. It was like having the best of both worlds!
But wait, there’s more! The Merrell MTL Skyfire 2 also boasts eco-friendly features that are worth mentioning. With 100% recycled laces and webbing, these shoes are a responsible choice for environmentally-conscious runners. As someone who values sustainability, I couldn’t help but appreciate this aspect of the shoe and the effort Merrell has put into making a more environmentally-friendly product. It’s a win-win – not only do you get top-notch performance on the trails, but you also get to feel good about making a sustainable choice. Kudos to Merrell for their commitment to the environment!
