Notable elements of the New Balance Summit KOM GTX

- One of the upgrades that trail running shoes usually get is the addition of a waterproof feature. The New Balance Summit KOM is among these shoes, as they introduce a GTX version of their well-liked trail runners. In a nutshell, the shoe retains the structure and features of the original Summit KOM and is just taken up a level with the inclusion of the Gore-Tex membrane.

- The upper, apart from the Gore-Tex waterproofing, still possesses the same look and feel, which is due to the breathable mesh that provides a sock-like fit. The sole unit also retains the features of the original shoe, which includes a REVlite midsole and the well-known, durable Vibram outsole.

Size and fit

Although the New Balance Summit KOM GTX claims to be true-to-size according to their website, many customers have found the shoe to be narrow-fitting and, thus, necessitated a size up to fit comfortably. This may not apply to everyone, so it is best for buyers to try the shoe from a store to ensure accurate sizing. The Summit KOM GTX model is specifically made for men and is available in men’s sizes, as well as men’s width options of D - Medium and 2E - Wide.

Outsole

The MegaGrip outsole variant of Vibram has always been popular for its unparalleled traction and durability. The outsole provides maximum ground contact, yet also reinforced on the shoe’s high-wear areas.

The unique tread pattern of the Vibram MegaGrip outsole allows for multi-directional grip, especially on uneven technical trails. The outsole’s lugs have ample space between one another to ensure flexibility without the loss of traction.

Midsole

REVlite is one of the reliable shoe technologies of New Balance running shoes, and with the Summit KOM GTX, it delivers the same steady ride and lightweight cushioning that runners are familiar with. REVlite is made from refined ethylene-vinyl acetate (EVA), which ensure 30% more comfort, responsiveness, and durability that the industry standard. This tech is available in other popular New Balance runners, such as the 890 v6.

A Rock Stop plate is placed in between the REVlite midsole and the outsole. This feature protects the foot and offers stability by dispersing impact during landing. It is especially useful when running on uneven surfaces, such as rocks and debris.

Upper

The mesh upper of the New Balance Summit KOM GTX promotes adequate air circulation. It has tiny pores that prevent debris from entering the shoe, but not at the expense of ventilation. The mesh is combined with synthetic materials on the sides of the shoe, which act as overlays that provide support and structural integrity.

The Summit KOM GTX gets an extra layer of upper in the form of a Gore-Tex membrane. Aside from additional foot coverage, the Gore-Tex serves as a waterproofing detail to keep water and other wet substances from getting to the foot.

A Toe Protect forefoot guard is placed at the tip of the shoe. As the name implies, this detail protects the toes from injuries that may result during running on the trails.
