Good to know
- The unpredictable nature of the trails needs a product that is up to the task. The Merrell Fiery offers form-fitting security, underfoot support, and trail surface traction. It takes inspiration from classic off-road runners as it has a bulky yet highly protective design that serves as a barrier against debris, uneven ground, and other hazards.
- Ethylene-vinyl acetate (EVA) is a compound that is used generously in this product. The full-length cushioning system is made of this industry-standard foam, as well as the removable contoured footbed. Acting as the external pad is Merrell’s own M Select™ GRIP, a layer that is tasked with providing traction and shielding.
Runners are welcome to make a purchase decision using their usual sizing expectations because Merrell has designed the Fiery to have a true-to-size configuration. However, it may prove essential to test the shoe first or read reviews that tackle the in-shoe feel to fully get an agreeable in-shoe experience.
When it comes to the sideways fit, runners can appreciate a snug wrap because of the presence of a multilayered mesh and a bevy of hot-melted overlays. Nevertheless, the brand touts the ghillie lacing system as an element that averts a too-restrictive hug.
M Select™ GRIP serves as the outsole unit of the Merrell Fiery. This compound generously covers the bottom part of the midsole foam, acting as a barrier between the cushioned piece and the potentially abrasive outdoor topography. Also, it has a naturally grippy nature which allows it to maintain surface control, even when tackling the uneven nature of the trails.
Aggressive gripping lugs pockmark the external pad. These prominent nodes have angular surfaces and clamp-like ends to heighten the grip on the ground. They can also potentially extend the lifespan of the shoe through their thick construction.
EVA is an industry-standard cushioning unit that runs the whole length of the Merrell Fiery. This element offers responsive cushioning and energized toe-offs. It also has a mildly flexible construction to accommodate the natural motion of the foot as it goes through the gait cycle. EVA is used by many running shoe series, including the well-known and trail-optimized Hoka One One Speedgoat family.
An EVA footbed separates the foot from the lasting board of this shoe. The soft surface of this accouterment is for the perception of an accommodating step-in environment. It also adds a bit of oomph to the quality of the cushioning. It can be removed or replaced with a new one if the wearer wants to do so.
A multilayered mesh serves as the facade of the Merrell Fiery. This material has the job of securing the foot and maintaining cool and dry coverage.
Synthetic overlays are printed onto the silhouette, with some sections connecting to the ghillie lacing system. A snug and secure wrap is the goal of this design.
