Engineered for city running, the Undefeated x PureBoost RBL ‘Shift Grey’ carries a lightweight knit textile upper finished in dark grey. The look is accented by floating Three-Stripes and nubuck heel pieces, with ‘UNDFTD’ lettering that wraps around the elastic collar. The nylon heel loop displays Undefeated’s Five Strikes emblem, while a crisp white Boost midsole offsets the dark coloring up top.
