The adidas Terrex Free Hiker boot adapts the brand's athletic innovations to the trail in a utility-inspired design. Revealed in March 2019, this 'Black Tan' iteration provides an adaptive fit in a water-repellent Primeknit upper with patterned laces, protective synthetic reinforcements and an EVA cap to stabilize the heel. The responsive Boost midsole and grippy Continental rubber outsole join forces for all-conditions performance.
