A simple boot with clean lines. The Sienna ankle boot stands out with its minimalist silhouette, a protective coating along the edge of the shoe, and our clean-lined TrueSense® GS1 sole. Elastic inserts make it easy to slip on and off, while the Zero Drop design provides a secure, natural stance. Understated, functional, and versatile—a boot for every day.
