BERTIL Derbies play the balancing act between the universality of a calfskin derby and the audacity of its sole, between the finesse of the leather and the contrasting micro block. The articulation of the sole helps the foot roll, perfect for the woman who is on the run all day, without compromising on elegance. Lace-up derbies in calf leather, black color. Ultra-light EVA micro block wedge and articulated sole, charcoal grey color - Clergerie Signature.
