Updates to Adidas Terrex Fast R GTX

  • Adidas’ rugged and versatile Terrex Fast R GTX just got better in this new version. Runners will have a faster and more convenient time with the new speed laces that are made of very tough material. A quick toggle of the laces and runners get their best and most personalized fit.
  • For better ground feel and to make it nimbler than the prior version, Adidas lowered the profile of the shoe. With a lower stack height, the 8mm heel drop will be maximized for smoother and quicker transitions while stability increases as the foot is not as elevated as before.
  • The outsole gets a boost with super aggressive lugs with generous spacing. Running downhill or uphill will be a cinch due to the extremely sticky rubber compound from the German tire maker, Continental as well as Adidas’ own Traxion. The specifically-designed spacing of the lugs enables the shoe to shake off mud and keep it from weighing more when any muddy trail comes along the way.

Adidas Terrex Fast R GTX size and fit

The fit and sizing of the Terrex Fast R GTX are reminiscent of the original model that was introduced in 2012. It has an average room in the heel with a really snug midfoot. The toe box has ample volume and width that makes the shoe ideal for mid to long distance runs. Medium is the available width of this shoe. Sizes are from 7 to 14 for the men’s and 5 to 11 for the women’s.


Outsole

Adidas continues to work with giant tire manufacturer, the Continental, in producing rubber outsoles that are based on the compound used in bicycles that deliver superior grip and durability. This is the same compound used in the Fast R GTX that has 30% more bite on wet or dry surfaces. Adidas’s own Traxion compound is used in the outsole for a truly outstanding traction on the trail. The Formotion technology is also at work in the outsole as evidenced by a decoupled heel that helps with shock absorption.


Midsole

Adidas’ signature AdiPrene+, which very light and durable, mans the forefoot for really responsive cushioning and enhanced toe off. The Formotion midsole helps with the cushioning and makes the transitions smoother.


Upper

The upper is made of breathable and abrasion-resistant mesh that adapts well to the runner’s foot. Giving support to the upper are overlays running from the midfoot to the area between the forefoot and midfoot. The new speed laces are directly connected to the overlays, which really enhance the locked in security of the Fast R GTX. A molded Ortholite Sockliner makes step-in comfort plush while the EVA-made and molded tongue elevates the sock-like feel of the upper. The Gore-Tex membrane below the mesh offers waterproof protection without sacrificing ventilation.
