Black Block Heel Ankle Boots A black ankle boot is a certified wardrobe essential, but the latest footwear offering from Carvela considerably raises the standards by throwing a few contemporary features into the mix. Neatly positioned on a block 60mm heel, Sabel is a stylish, yet wearable boot, subtly attracting attention (and compliments!) with its textured ankle details, gold side zip fastening and material-mix construction. Finished with an almond toe, this timeless boot passes the day-to-night transition test with ease, effortlessly complementing a range of tried-and-tested looks, from staple skinny denims and graphic tees to colourfully patterned shift dresses paired with chunky jewellery.
