These were purchased recently. I have a couple of pair of Birki Clogs that I've had for years and wear them a lot when I am working in the garden, running errands, or whatever. They still look good and I really didn't need a new pair so these were an impulse buy. I liked the skull and crossbones pattern and figured they would be great for Halloween.
These shoes run large. Since I already knew that I needed to size down a half size, I ordered these in 39 which is normally the equivalent of a women's size 8 1/2.  My normal Birkenstock size is a 40. The shoes provide adequate toe room and aren't constrictive. I have a medium foot width and they'd probably work for most people. They are really comfortable and provide a lot of support as I am on my legs a lot. I even wear them indoors because I like the way they feel. I normally toss my solid colored Birks in the washing machine when they get dirty and then air dry them, but I suspect I am going to have to wash this pair in the sink or hose them off because of the design. So if you are going with a pair that has a design I'd avoid the washing machine.
I paid $50 for this pair and that seems to be the going rate though you can sometimes snag a deal on the net and pay a little less.
