Love this stylish boot!
Size: 9.5, Color: Black Wc
Stylish boot with low heel. Good suede and rubber no-slip sole. I purchased wide calf and they fit well. My calf measures 16.5 inches. I purchased also in brown and chianti colors.

Returned
Size: 8, Color: Spiced Nutmeg Cs Wc
The suede and color were great but the boot didn’t fit. The calf fit was way too big and the toe was so pointy it felt and looked weird to me - made my foot feel cramped and looked like I was wearing two sizes bigger. The heel was nice though.
