I work as Opschwester and stand for hours in these shoes. I had as a child to an accident and therefore always problems. Also, I've prepared a heel spur of my big problems especially in the Opclogs. These shoes are the solution. I have no more, and also a 10 hour day no pain aching feet more. Those things are now at least 100 x in the shoe washing machine (at 60 degrees) and are still as good as new. I can only recommend the shoes and they give me my daily work much more convenient. However, actually order one size larger!
