These grey adidas Terrex Free Hiker Parley hiking sneakers have been made with upcycled plastic bottle waste. Featuring a sock-like fit and a Primeknit upper, they boast a round toe, a lace-up fastening, a rear pull tab, an EVA stabilisation frame and a Boost midsole. Complete with an all-terrain Continental rubber sole, we say rocks beware - these adidas trainers are about to walk all-over you.
