Sibilla Block Heel Zip-Up Boots for Workdays

Sibilla is a block heel boot that zips at the side, cut clean with no laces, buckles or hardware anywhere on it. The block heel gives height with a stable base, and the zip means the boot goes on in one movement. It is the sort of boot that gets worn four days a week precisely because there is nothing on it to tire of.

Black, brown and grey. Black is the workhorse and handles tights, dark trousers and a winter coat. Brown is warmer and looks better against cream, camel and mid-blue denim. Grey sits between the two and works with a cooler palette. All three are plain enough to wear to an office, a dinner or a full day of errands without looking like a different register of shoe.

Sizes run US 4 through 10, eight steps. These run true to size. The chart below converts each available size to EU and UK alongside the foot length it matches. There is no stretch anywhere in the construction, so if you sit between two sizes, measuring your foot is more reliable than going by the size you usually buy.

• Silhouette: mid-height boot
• Heel: block heel
• Closure: side zip
• Toe shape: round
• Colourways: Black, Brown, Gray
• Sizes: US 4, 5, 6, 7, 8, 8.5, 9, 10

Foot length is measured heel to longest toe. Runs true to size, so order your usual size and go up half a size for a roomier fit.
