The Consensus
Technologies
Outsole
- First of all, we find Quantum Grip on the outsole of the Merrell MTL Skyfire. This is a durable rubber designed specifically by the brand for the mountain. It allows the athlete to tackle the most difficult trails with confidence thanks to the shoe’s impeccable traction.
Midsole
- The midsole is equipped with EVA foam. Ethylene-vinyl acetate is a material known for its lightness and natural cushioning which is used in many sports shoes. It protects the foot from stones and the roughness of natural terrains. This platform promises a springy and fluid ride.
- In addition, there is a rock plate that protects the foot from potentially dangerous rocks on trail terrain. This also improves the durability of the shoe.
- Finally, the EVA foam sockliner conforms to the shape of the foot and completes the cushioning.
Upper
- The upper of the Merrell MTL Skyfire features an engineered mesh with TPU overlays. This configuration is designed to effectively lockdown the foot during training for optimal comfort. Perforations throughout the mesh ensure good ventilation to prevent your foot from overheating during exercise when you’re going faster.
- The inner mesh lining feels soft to the skin and helps the foot breathe in the shoe.
- There is also an internal bootie that allows the foot to be wrapped comfortably and flexibly. In addition to preventing chafing irritations, it also provides a better fitting foot lockdown.
- In addition, the external molded TPU heel counter comfortably locks-in the heel for a more comfortable and effective foot lockdown during running.
- Finally, the reflective details allow the runner to be seen even at night for more safety.

Frequently Asked Questions (FAQs)
This trail shoe follows a standard sizing system. Trailers who have tried it on confirm that it runs true to size. So you can choose your usual size for trail shoes. However, if this is your first pair of Merrells, a visit to the store can be wise to be sure to choose the best size.
To date, only one study has investigated the relationship between weight, sole thickness, and risk of injury. According to the conclusions of this study, minimalist shoes can increase the risk of injury for runners weighing more than 71 kg/157 lbs. Apart from this, there are no recommendations for other categories of running shoes. The MTL Skyfire has a stack height of 24 mm under the heel and should, therefore, be suitable for everyone.
This Merrell trail shoe is mainly recommended for short to medium distances at high speeds. However, it remains suitable for longer distances and at a slow or moderate pace. For ultra-trail, there is no special indication. If you find this shoe comfortable during your long runs, there should be no problem.
This model is available in two versions: Gore-Tex and standard. Thanks to its water-repellent nature, the standard version is designed to fend off small water infiltrations and dry quickly. Therefore, your foot should stay dry if you are running in light rain and passing through puddles. If the rain is heavier, your foot may get wet after a while. The Gore-Tex version offers better protection and keeps your feet dry even in heavy rain or when crossing shallow streams. However, we should note that the Gore-Tex version is a little more expensive and heavier. It’s up to you to see which one suits your objectives. The standard configuration has the advantage of offering sufficient ventilation of the foot during the effort and being lighter and more flexible.
