I have been wearing Okabashi flip flops and sandals for a few years now so I thought I would get the clogs for work. I am on my feet most of the day and these are comfortable all day, my feet don't hurt at the end of the day, they are work appropriate, and they are made in USA. Did I mention they are affordable? These are way better than any Dansko shoe out there. Great for working in a hospital.

Now about the size, I usually wear about a 7.5-8 in US womens shoe, I ordered a ML and they fit perfectly.
