Cute but Ouch
Size: 8.5, Color: Sand
Theses shoes are cute and comfortable to walk in *comfortable to the soles of your feet* HOWEVER, there is part of the inside seem on the outer right ankle that scrapes my leg with every step. I tried to see if wearing them down would help, wearing band-aids, putting duct tape on my leg, mole skin - but nothing helps, by the end of the work day I still feel that scraping seem. And I'm not usually sensitive to this kind of thing. I'm way outside my return window, so I'll have to pass them along to someone else with my same shoe size or donate them. Overall they're a good shoe - i just think mine had an issue when the seems were finished

Size down 0.5!
Size: 8, Color: Black Lizard
Love the black snake skin look, I normally wear a size 8 and these fit more like an 8.5. Works with a thicker sock but I definitely recommend sizing down 0.5.

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.
