I have been a nurse for over 20 years I have worn them all Nurse mates, SAS, cherokee, reebock, nike, kswiss, quarks. To show you how long I have been on my feet I was wearing EARTH shoes back when they were "IN". I've done dansko (a pair which I feel walking to the parking lot and broke my ankle on graceful I know) I have clarks, I have Finn Comfort. I have also gained and gain lost and gained weight again over the years. The one shoe I wear now both at work and off work is Birkenstock. They may not look like much but at the end of the day I can still walk.
