Notable elements of the Adidas Terrex Speed LD

- The Adidas Terrex Speed LD is a trail running shoe that’s made to provide versatile performance. The outsole unit is made of Continental rubber, a material that’s commonly used for the tires of vehicles. Such an inclusion aims to heighten durability and traction. A full-length ethylene vinyl acetate (EVA) foam is used for the midsole unit.

- A breathable and abrasion-resistant mesh is used for the upper unit of this product. It is supported by a mix of printed overlays on the forefoot and stitched layers on the rest of the façade. This blend of elements has the purpose of holding the foot in place and protecting it from wobbling.

- The Terrex Speed LD is fundamentally the same as the original Terrex Speed model save for a colorway change that signifies a partnership between Adidas and White Mountaineering, a Japanese fashion label.

Size and fit

The Adidas Terrex Speed LD was constructed to be true to size. Runners can use their typical sizing expectations when considering a pair. It is worth mentioning that trying on the shoe first before making a purchase decision can contribute to a satisfying in-shoe experience.

When it comes to width, the available options are D – Medium and B – Medium for men and women, respectively. Low and medium foot dimensions are the ones who are welcome inside the interior chamber of this Adidas trail running shoe.


The outsole unit of the Adidas Terrex Speed LD is made up of Continental rubber. This layer is tasked with protecting the midsole from wear-and-tear. It also provides long-lasting traction as it has a durable construction and a distinction of being a material that’s used for car tires.

A slew of traction lugs pockmarks the surface of the rubber pad. These prominent nodes are designed to improve the grip of the shoe on unpredictable terrains. Their opposite-facing structures benefit upward and downward traversals.


The underfoot cushioning is the responsibility of the ethylene vinyl acetate (EVA) foam, a feature that runs the entire length of the Adidas Terrex Speed LD. EVA has a lightweight and reactive construction which allows it to support the foot throughout the running session. It is also flexible enough to welcome the natural movement capacity of the tendons and muscles. Many products use this industry-standard foam, including popular ones like the Hoka One One Clifton 5.

An insole is placed right above the lasting board of this product. The purpose of this add-on is to act a soft surface for the underside of the foot. It also offers some extra cushioning. It can be removed or replaced with a new one or a custom insert if the runner chooses to do so.


The upper unit of the Adidas Terrex Speed LD uses a mesh that is resistant to abrasion. This material embraces the foot and keeps it secure. It has several breathing pores to permit air into the foot-compartment. Furthermore, it is lightweight and flexible.

The toe box and the ends of this product’s vamp feature printed overlays. These thin layers are meant to shield against rocks and other jagged surfaces. They also bolster durability by preventing the mesh from tearing.

The midfoot and the heel have stitched-on overlays that directly help the lacing system when it comes to centering the foot and preventing it from wobbling. These external sheets are also meant to avert accidental shoe removals.

This shoe doesn’t have a traditionally separate tongue unit. Instead, the opening is a one-piece unit that points out the seamless configuration of the silhouette. The instep section has a protrusion that mimics the end of a shoe-tongue.

The interior lining is comprised of a smooth textile, the use of which is to improve the feeling of being wrapped in a sock-like cover system. This sleeve has some padding in it, but it doesn’t sacrifice flexibility nor breathability.

Flat shoelaces snake through isolated eyelets on the edge of the lateral and medial overlays. Such a design helps to adjust the fit to follow the preferences of the runner. The perception of tightness or looseness is controlled via this lacing system.

Pull tabs are added to the front and back of the one-piece opening. These fabric loops assist the runner in widening the entry point of the interior chamber, thereby quickly facilitating the foot into, or out of, the shoe.

The ‘adidas TERREX’ words are emblazoned on the lateral side to amplify recognition of the brand and the product.
