The Pro XP is Dansko's answer to my perfect shoe. It has great arch support, a cushioned footbed and a firm construction. The high arch keeps pressure off the heel and ball of my foot, and the padding lets my heel relax and also removes the pain from callouses that build up on my feet. And of course, the rocker bottom allows me to stand and walk with ease. I'm on my feet at least 14 hours a day and my feet never hurt when I finally take them off!
