Josef Seibel Women's Sienna 09 Ankle Boot Camel The Sienna 09 is a modern cross between a Chelsea boot and lace-up boot. The laces mean you can get the perfect fit while the elastic panels give you increased flexibility. Slightly burnished for style, the supple leather will only look better as it ages. The boot�s slim silhouette is paired with a wood-effect sole for the ultimate style and grip. Josef Seibel Women's Sienna 09 Ankle Boot Camel
