The Secil is an ankle boot crafted from black leather with two zipper details. Sole height: 30mm. Zipper on the outer side. A brand-new design for Carvela this autumn/winter, Secil looks set to be a best-seller already. Designed in butter-soft black leather with a completely fuss-free upper, this versatile ankle boot features a flattering round toe, and a wearable block heel with a side zip to make light work of slipping these on and off.
