Black Block Heel Ankle Boots Chunky chic is at the forefront of every high-end collection this season, and Carvela Comfort's new Royal boot is every bit as spirited as its name suggests. Crafted in the richest black leather for premium elegance, this fresh spin on the Chelsea boot features modern elasticated gussets at each side which, with the added bonus of a rear pull tab, make them super simple to slip on and off. The blocky 85mm heel might seem vertiginous at first, but a subtle platform shaves off the drama to make them endlessly wearable.
