Name: Adidas Terrex AX4
Brand: Adidas

Our verdict

An exceptional budget-friendly day hiker—this is how we view the Terrex X4. Indeed, from its virtually tackle-anything underfoot performance to the way it handles shifting weather, we find this piece from Adidas is a doozy. There's also its initial price of $90, which makes owning one not at all an uphill battle.
