Responsible Collection: Recycled/Repurposed Upper Material: 50% recycled polyester, 50% Parley Ocean Plastic Closure: lace Footbed: EVA Midsole: BOOST For that free feeling on the trail, we like the lightweight and comfortable Adidas Terrex Free Hiking 2. The soft, PRIMEKNIT collars have a sweet sock-lite fit around our ankles with the EVA support and BOOST midsoles spoiling our feet with plush cushioning for hiking trails, gravel, and forest service roads. On top of all that comfort, Adidas has scored some environmental points by crafting the shoe's uppers out of recycled polyester and Parley Ocean Plastic that removes plastic pollution from our oceans.
