Loved them so much- Bought another pair
To start off, I have wide feet, ankles, and calves, because i'm a bit on the heavier side. Finding shoes that fit these requirements are difficult. The top part of the shoes that hug my legs are actually still a little roomy. Someone who has slightly larger lower legs can fit into these as well. If you have tiny legs, these shoes may be a little too loose, or if you don't have wide feet. These shoes are literally perfect for my feet and legs. The back unzips so I was able to get my feet into the shoes easily, and even wearing them I didn't feel like my toes were being squished. I ordered a size 10, and it is perfect length and width for my wide feet. Do note: My feet are wide enough to not fit in most shoes, but not too wide, you should pay attention to the measurements if you have wide feet.
I was a little skeptical from a review of a woman who had her toes bleeding from these shoes, as I know that is often a problem for me with most shoes I wear. Generally I start bleeding in the back of my heel. So I was skeptical that these shoes would make me bleed. However, I was proven wrong. These are one of the only shoes i've worn that haven't rubbed my skin right off. I believe that has to do with the lovely height of the back, which prevents rubbing on the back of your heels, and the perfect width of the shoes. If your feet are too wide for these shoes, then you will probably bleed, but that's to be expected because the shoe does not fit you and that is often something that can happen with shoes that don't fit.
I originally bought the green pair, because I loved the color, but then I loved the fit so much that I bought a second, black pair. These are one of the only shoes with heels I actually wear because they are more comfortable than most, and they're just adorable. I am not generally a high heel wearer, so I'm not used to walking with my heels elevated. Despite that, these shoes were fairly easy to walk in. They are my favorite pairs of heels. and I do highly recommend them.
I will be buying more colors in the future, and I hope they will come out with more colors like brown and an aqua/blue shade.

Trying to get what's in picture
Size: 9, Color: Natural Nbpu
Amazon said my size was a 10. So i ordered a 10. Waaaay too long, wide big in general, and I have a wide foot so I was pleasantly surprised. Company did not offer any color in size 9.5 but according to their size guide I "might" fit into a 9! Again, pleasantly surprised that i totally did and even when I put in my "Dr. Scholl's" inserts, i have slight wiggle room for when feet swell. Overall I am happy with the shoe fit, comfortability and height...not that I'd wear these for more than 8 hrs., but comfy enough for a wedding or to wear to work when I have a "mostly office day" instead of out in the yard. HOWEVER... i loved the color and suede-ey look/feel pattern of the size 10. It was exactly as picture/info described. But I'm not sure what happened to the size 9? wth? Although i ORDERED exact same shoe/color but in smaller size...what I got was a much lighter color, and NOT the suede fabric...more nubuck. Bu inside of shoe had same info/tag as the 10. Really hoping that it was a packing/labeling error. Will try one more time to order the 9, in the same 'name' fabric. Fingers crossed that I get what I ordered/want. Otherwise it'll be a return and less stars.
