Notable elements of the Salomon Trailster GTX

- The Salomon Trailster GTX is an apparel that’s made for those who like to take to the off-road paths. The silhouette has a sporty yet fashionable design, with mostly synthetic prints bolstering the mesh on its frame. Stitched-on reinforcements are placed on the heel to help with the security of the foot. A waterproof layer differentiates this model from the original Trailster model.

- Underfoot cushioning is the responsibility of the ethylene vinyl acetate (EVA) foam. This full-length piece is responsible for attenuating impact shock and energizing the toe-off. It is covered by Contagrip® MD, a rubber specifically made to handle both soft and hard ground.

Size and fit

The Salomon Trailster GTX was made using the standard measurements. When it comes to size, runners can choose from full and half-size variants while also considering their usual size expectations.

Widthwise, the selections are D - Medium and B - Medium for men and women, respectively. Those who have low and regular foot dimensions are the ones who are going to enjoy the in-shoe experience.


Contagrip® MD is the technology that is used for the outsole unit of the Salomon Trailster GTX. This rubber layer is tasked with protecting the midsole foam from the abrasive nature of the outdoor topography. It even has a generous thickness to allow it to last long.

While rubber is naturally grippy, it alone cannot fully control the quality of the movements on the unpredictable surfaces. Some texturing and design upgrading is also needed to accentuate the clamping capacity of the platform. Gripping lugs are the embodiment of such performance requirements as they deliver an omnidirectional grip that benefits the runner when traversing irregular paths.

Flex grooves are patterned on the forefoot section of the external pad. These shallow canals aim to make the foam midsole as flexible as possible, thereby giving slack to the natural bending ability of the foot and its joints.


The midsole unit of the Salomon Trailster GTX is made of ethylene vinyl acetate (EVA). This cushioning technology runs the entire length of the shoe, encompassing the foot and keeping it secure and well-supported at all times. EVA is an industry-standard material used in many of today’s selection of running shoes, including the ever-popular Hoka One One Bondi line.

A die-cut OrthoLite® sockliner is placed on top of the primary cushioning unit. This add-on offers extra support and a feeling of softness against the foot-pad. It is lightweight, flexible and able to blend with the rest of the platform. It has antibacterial and anti-moisture capacities to maintain a healthy and odor-free compartment for the foot.


Mesh material is used for the upper unit of the Salomon Trailster GTX. This multilayered cover system offers a secure wrap that doesn’t limit breathability. It has visible breathing holes all over its surface to allow the flow of air into, and through, the foot-chamber. The multiple layers act as shields against small debris on the trail.

GORE-TEX® is a waterproof membrane that coats that upper unit. This accoutrement is meant to stave off water infiltration when traversing wet environments. Its presence is near-impossible to notice in the shoe, and it doesn’t mar the ventilation, as well.

Sensifit™ is an overlay technology that involves printed overlays fashioned in an outstretched-finger-like pattern. The synthetic prints bolster the structural integrity of the upper unit, yet they also help the lacing system when it comes to securing the foot and keeping it from wobbling. The instep part has eyelets that directly connect the Sensifit™ to the crisscrossing fit-adjustment system.

Flat shoelaces snake across the bridge of the upper unit, engulfing the throat and the roof of the shoe. These strands manipulate the tightness or looseness of the fit, allowing for a customized in-shoe experience that doesn’t mar the security of the foot nor the freedom of motion.

The tongue and collar are padded. These elements of the upper unit are tasked with providing cushioning to the topmost portions of the foot, including the Achilles tendon, the ankles and the bridge of the foot. They also prevent in-shoe quivering during the run, as well as fatigue caused by the impact shock generated by the act of striking the foot on the ground.
