Comfort+pointed toe=Sam Edelman
Size: 6.5, Color: Dk Chocolate
These are without a doubt the most comfortable shoes/boots, I with a pointed toe, that I have ever worn. The heel is a perfect height to elevate your look without forcing your foot too far forward into the toe box. I have worn these all day long, and have never had them pinch my toes. I’ve even worn them walking through cobblestone streets in London without discomfort. These boots also look amazing with a skirt, dress, or even a pair of jeans. The color is rich and the suede is butter soft. They fit true to size. I wear a 6.5 M. I find this true with all of the shoes I own from Sam Edelman. The quality is much better than the price suggests. I highly recommend these boots. You won’t regret your purchase!

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.
