Beautiful, Versatile Boot
Size: 8.5, Color: Cyprus Tan
Versatile boots for business wear. The calf profile is sleek and slim so they are wearable under straight cut pants but also look beautiful paired with a midi skirt and sweater.
I am 5’6” and 145 lbs. These stop right below my kneecap and have just enough room in the calf to slide up my leg but stay in place. I am usually a size 8 and originally purchased an 8 in these boots but found the toe too short and narrow. When I sized up to an 8.5 the toe bed was comfortable and roomy. Heel is just high enough to give a dressed up look but is still comfortable to walk in.

Slyvia boot is a great looking pair of boots
Size: 8, Color: Black Leather
These are a great pair of boots that run true to size. Genuine leather as they do conform to fit. Hell height is perfect on these boots and are wearable 6 to 8 hours easily with no pain. I make sure to condition the leather on my boots before wearing and after every 2nd to 3rd wearing stuff the bootsto store them.

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 ❤️!!!
