Comfortable and well made, but the white color is off
Size: 8, Color: Sand
I've owned the microsuede sand boots for over and year and they're very comfortable. I don't wear them a ton, just for a few hours here and there to church. But after a year they have no scratches or nicks, they've held up well. I just ordered them in white. They are beautiful boots, but they're not a true white. They're more of an off white. Also - be aware - they are designed with little squares all over them that are hard to see in the pictures - you have to look at them in the 3D view to see them. I liked the pattern and the look of the boots, I just wasn't happy with the color. I'm so disappointed - I returned them.

Surprisingly wide enough
Size: 9, Color: Black
Was surprised that they're wide enough. Usually, shoes that say they're wide, aren't really wide. They're very cute and "hopefully" when I do wear them out, they'll continue to stay comfortable. I ordered both the Coffee Bean and Black, size 9. Usually wear a 9 or 9 1/2, the fit has plenty of room in the toe area with size 9.

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
