Calf shaft runs big
Size: 9, Color: Black Wc
Beautiful suede boots. The shaft does run a bit loose so if you’re on the fence about ordering a wide version you may want to try the regular size first. I sized up half a size so I could wear a sock but probably didn’t need to. The kitten heel height is perfect for my comfort. I liked these so much I got them in dark walnut and black.

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.

Disappointed I ordered them thinking they would arrive when they said they would and they did not! Ordered two pairs and run extremely big!

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.
