Notable elements of the Adidas Terrex Speed GTX

Continental™ Rubber is a technology that’s used for the Terrex Speed GTX’s outsole. This technology provides protection to the shoe. Due to its durability, it helps prevent abrasive elements from tearing through the shoe. Employed on the outsole are the ground-focused lug patterns of the shoe. These help in the grip and traction of the shoe on various surfaces. 

The shoe’s lightweight quality can be attributed to its midsole composition as it is made of ethylene-vinyl acetate (EVA) foam. The material is known for its natural durability and lightweight feature. This midsole provides added cushioning and comfort to the foot.

For its waterproof and windproof feature, the shoe employs Gore-Tex® upper, which is essentially made out of waterproof, breathable fabric. This technology disables wet elements from entering the shoe while allowing water vapor to pass through. This also gives the Adidas Terrex Speed GTX exceptional flexibility. 

Size and fit

The Terrex Speed GTX is available in unisex sizing. The technical elements of the shoe that directly affect its fit include the textile and synthetic upper of the shoe that allows the shoe to basically adapt to the foot of the runner while providing security. Moreover, the lace-up fastening system of the Terrex Speed GTX also plays a crucial part in the fit of the shoe; this gives the shoe a locked-down feel. 

Proper fit and sizing of this shoe may be achieved by making sure that one tries on its fit first before proceeding to purchase. Going through various tester and expert reviews can also be of help when it comes to finding the right size and fit. 


The Adidas Terrex Speed GTX employs Continental™ Rubber outsole, which is known for its durable components. This technology allows the shoe to tread through both wet and dry surfaces while still providing superb grip and traction. This technology basically acts as an added layer of protection to the shoe as it prevents abrasion from different elements. 

The outsole of the shoe also utilizes ground-focused lug patterns. These are the components that promote the grip and traction of the shoe on different terrains. 


EVA foam makes up the midsole of the Terrex Speed GTX. This foam is known for its lightweight and durable properties. This helps add cushioning to the shoe, which promotes comfort. It also employs shock-absorption qualities assisting the foot to propel forward at a higher speed.
