Good to know

- The Merrell Fiery GTX is a trail running shoe that is strategically designed for neutral pronators. It utilizes the Gore-Tex performance shell. This feature of the shoe aims to provide a comfortable and breathable waterproof material that the user can use in both wet and dry weather conditions. This is significant in protecting the foot from being wet during the running session. 

With the utilization of the breathable mesh lining, the shoe guarantees a comfortable fit. Along with the leather-and-mesh upper, the runner will be able to experience a secure and supported fit when tackling a wide variety of terrains. 

The M Select GRIP outsole is integrated into the Merrell Fiery GTX. This component of the shoe aims to deliver an outstanding amount of durable traction. This material is essential in preventing any slippage during the running session.

Utilized in crafting the running footwear is the EVA midsole. The primary focus of this midsole compound is to provide comfort and stability. As a result, a more efficient and responsive running experience is enjoyed by the runner. 

Featured in the shoe is the EVA removable footbed. This material is focused on delivering additional comfort and cushioning during the running activity. Described as the inside part of the shoe, the footbed lies underneath the bottom of the foot. It has structural elements that provide a better fit, as well.

The Gore-Tex waterproof membrane is integrated into the upper area of the Merrell Fiery GTX. The primary purpose of this is to deliver a waterproof performance. It is also focused on providing exceptional breathability during the run. When the shoe is breathable, the foot is kept cool and dry at all times. 

Used in making the running shoe is the synthetic leather and mesh upper. This component of the shoe is meant to provide added breathability and durability.

Along with the mesh upper is the breathable mesh lining. This is significant in promoting a healthier and fresher foot environment.

When compared to the Merrell Trail Glove 5, which uses the ghillie lacing system, the Merrell Fiery GTX utilizes the traditional lace closure. This system is essential in achieving a lockdown feel during the running activity.

Featured in the shoe is the Bellows tongue. This tongue unit is vital in keeping debris out of the footwear during the runs. 

The protective synthetic toe cap is integrated into the Merrell Fiery GTX. The primary goal of this is to provide protection to the foot against hazardous materials that can be found on the trails. 

Utilized in the platform is the hyper-lock synthetic heel counter. Merrell added this feature of the shoe to ensure security and lockdown feel throughout the runs.

Merrell, the maker of the Fiery GTX, cares about the environment as much as other people do. The solution they have to protect the environment is to create vegan-friendly shoes. Merrell claims that one of these shoes is the Fiery GTX. This type of shoe aims to provide the right amount of support, durability, and traction that the user needs during the running session. With the footwear being vegan-friendly, Merrell ensures that it does not compromise the quality that runners expect from a trail running shoe.
