Buttery soft, comfortable and the perfect height!!!
Size: 10.5, Color: Black Leather, Size: 10.5, Color: Black Leather
I ripped these out of the box as soon as they arrived lol 😂 I knew they were the black knee high boots that I wanted to have as a staple in my Fall closet. They did not disappoint! The stitching is impeccable, they are buttery soft from top to bottom, they are the signature San Edelman design, the heel is perfect – it’s not clunky it’s sleek, but it’s not too high so you can wear these with pants and dresses and skirts. They are VERY COMFORTABLE!!! They are pointy - but I sized up a half so they are not squeezing my foot at all. I can move my toes around and there’s enough space for socks if I need to wear them. I am in ❤️!!!

These boots were made for walking…
Size: 9, Color: Chocolate Brown
Stylish black suede boots with an adorable chunky heel. The fit is true to size. They look elegant yet dangerous! They were also, surprisingly, very comfortable!

My favorite boots ever!
I searched forever to find the perfect camel boots and could not be happier with this purchase. So happy, in fact, that I bought another pair in a different color! They’re really soft and the perfect heel height to still be comfortable. They are so classy and definitely a staple for me for work. Love!

Not comfortable for long term wear. No cushioning .
Size: 10.5, Color: French Burgundy
So cute but too small for calves and no cushioning inside. Couldn’t walk in these for very long.
