Terrex, by sportswear giant Adidas, is a renowned trail running and outdoors brand, with over three decades of heritage. From trail running shoes and trainers to hiking boots, clothing, and accessories, Adidas Terrex is a great brand for blending urban styling with dependable outdoor performance.

The Adidas Terrex Swift R3 Gore-Tex is a robust hiking shoe that will chew up the miles spent in cross-country and off-trail terrain.

Terrex sports shoes are waterproof hiking shoes with a very light low cut. Regardless of this, they provide excellent protection and stability.

Fit and Sizing Doing a quick online search of the Adidas Terrex AX4, you'll see a fair number of users reporting the shoe runs small, and I found that sentiment to be mostly true. I typically wear a size 9 and have a slightly narrow heel and average-width forefoot and wound up ordering my usual size.
