I have had 4 pairs of Birks. I love them, but I have always been afraid to wear them to the park though! Silly, I know. I said this past summer that I needed a new pair and I didn't get them. I WILL get them before we go in June. I'll have to keep my eye on QVC. They have some good prices and sometimes a Today's Special Value on them.
Birks are the best shoes in the world for wearing in the parks or any time when walking a lot.. ok, that is what I wear almost always! LOL... did you see that black pair I wore with my formal on the cruise? I even have a couple of pair that are closed toes for winter wear... feet used to hurt all the time, since going with almost always birks, they don't hurt anymore.
Famous footwear has them sometimes... if you keep an eye out for their buy one get one half off sale you can sometimes get a good deal on them there too.
