Got them thurs evening and wrote them to work Friday. I'm an occupational therapist in a very busy clinic so I'm frequently on my feet working with patients. By lunch, my ankle felt like it was rubbed raw because the shoe comes up very high and tight at the ankle bone even though I kept loosening the laces and my right heel hurt. The good news is that when I got home and took them off, my feet didn't continue to ache which has been the case with my 'comfortable' shoes. Might give them another try... Also, the sizing is true. I wear an 11, ordered an 11 and it fit fine.
