The Undefeated x PureBoost LTD ‘Shift Grey’ released in November 2018 as part of a larger running collection featuring both apparel and footwear. This PureBoost sports a 3D knit textile upper, accented with camouflage detailing on the tongue and heel that gives the nod to Undefeated’s signature military-inspired aesthetic. Full-length Boost cushioning and a flexible outsole work in tandem for a smooth ride.
