86 / 100 based on 6 expert reviews

  • 94 / 100 | Road Trail Run | | Level 5 expert

    I’ll keep this shoe at the front of my rotation and pick it for days when I know I’ll be on steep, rough terrain, wet terrain, mud, off trail or snow (when I am not really worried about getting my feet wet).

  • 85 / 100 | Road Trail Run | | Level 5 expert

    This shoe shines when the trail surfaces are challenging, wet, dry, frozen, traction is a whole new level with this shoe.

  • 82 / 100 | Gear Institute | | Level 3 expert

    Overall, our wear-testers felt Adidas was bringing something unique to the trail and pushing running technology forward, but had some concerns about fit, comfort and versatility.

  • 77 / 100 | GearJunkie | | Level 3 expert

    It hits a middle point between the minimalist models in my closet and more bulky trail shoes. I was comfortable for 10+ miles running in the Terrex X-KING, and the shoes excelled where the terrain got muddy and steep.

  • 90 / 100 | Blacks | | Level 1 expert

    We were most impressive by the level of grip, which as far as we were concerned surpasses any other shoe on the market. Unlike other deep lugged trail running shoes, the mud didn’t clog in the soles, keeping the shoes light, fast and stable.

     If you need traction more than waterproofing for your winter runs, these are your shoes.

  • The Terrex X King is an Adidas trail running shoe that’s created for technical trails and other off-road paths. It has been optimized to deliver a solid performance on the unpredictable topography. The outsole tread has even been designed to mimic mountain-bike tires, making it easier to take control of the surfaces.
  • The upper unit uses a durable mesh to provide long-lasting protection and coverage. Strips of fabric have been stitched onto the upper, acting as overlays and connectors to the lacing system. A thin EVA tongue provides additional comfort to the top of the wearer’s foot.
  • The mid-sole unit features a very lightweight foam that’s made from Ethylene vinyl acetate. It’s to provide responsive cushioning and protection from the impact forces when striking the foot on the ground. It’s removable, by the way.
  • Directly molded to the upper is an external sole unit, which is based on the design and structure of a mountain bike’s tire. Parts of it go up to the perimeter of the upper unit, basically adding protection while also keeping the foot in place. Gripping lugs mark the underside of the trail shoe, ensuring traction and surface control.

The Adidas Terrex X King has a standard running shoe length. It follows the preferences of runners when it comes to sizing. The available width is medium. It accommodates those with medium-sized feet. The semi-curved shape of this shoe mimics the natural curvature of the human foot.

Continental™ Rubber is the material used for the outsole unit of the Adidas Terrex X King. It’s one of the sturdiest technologies on the market and it’s made to function well on many types of terrain.

The tread has been designed to mimic the look and function of a mountain bike’s tire. Gripping lugs provide reliable traction on a variety of surfaces. It even has those thin, needle-like protrusions that’re most commonly seen in bike tires.

The rubber material used in this shoe extends to the upper section: the sides, the toe area, and the rear. It effectively acts as a shield against debris and potentially injurious surfaces. It also doubles as a support unit that prevents the foot from wobbling around inside the shoe.

Just like the popular Adidas Duramo 9, the mid-sole unit of the Adidas Terrex X King features a removable EVA foam, which delivers lightweight, responsive and long-lasting cushioning. It’s an industry-standard material, but it’s efficient and reliable. It doesn’t break down easily, making it effective even after many uses.

A mix of mesh and synthetic materials make up the main upper fabric of the Adidas Terrex X King. They’re durable yet soft. They protect the foot from dust and trail debris.

Fabric strips have been stitched onto the main fabric and connected to the lacing system. These overlays do not have substantial weights, so they won’t affect the overall weight of the shoe itself. However, they’re strong and are able to conform nicely to the shape of the foot.

A speed lacing system is used in this model, essentially removing the need to manually tie laces.

A thin EVA tongue provides lightweight cushioning to the top of the wearer’s foot. It also prevents any hot spots or irritation when adjusting the fit.
