I love this so much and I will be buying other colors, which is not my norm.  I wore these on a night out and had no trouble walking in them, and my feet didn't hurt when I was done. The heel is sturdy and a good size for walking.  The strap for the buckle is a bit stiff, but presented no problems in fastening, and wasn't uncomfortable at all.

Best of all, though, is the sole of this shoe.  It's non-slip!  I'm not sure if it's intentional or not, but it is.  I've bought so many heels that had chunky heels that should have made for easy walking but were so slick I couldn't even stand up on my wood floors without worry, much less go places in them.  There's no problem with these.  It's awesome.
