Black Chelsea Boots Bridging the gap between pared-back comfort and sophisticated style, Stifle is a welcome addition to your weekend capsule. Styled in a black hue for new-season interest, this Chelsea boot has been given a contemporary upgrade via an elasticated back section to hug the contours of the ankle and a glossy croc-print heel panel. Finished with a low heel, Carvela's latest spin on the ankle boot is designed to add modern polish to any casual ensemble.
