These boots are real comfy and the height of the heel is suprisingly comfy to walk on, and they're true to size.  Two negatives though:  the "patent leather" on the heel portion of the foot makes it a little bit tight and constricting, especially when walking up and down stairs; and, although the boots truly look "dark grey" online, they're actually slightly lighter in color in actuality.  But really, you can't beat a pair of Aerosoles!
