Sierra 90 BootCrafted in supple stretch sheep nappa, designed with seamless lines that contour the leg like a second skin. Featuring a bold square toe, sleek 9cm stiletto, and signature gold zip puller, its a refined balance of modern elegance and timeless luxury. This style is true to size. However, if you are between sizes, we recommend sizing down to ensure a snug, glove like fit. The softness of this leather will soften quickly with wear.
