I wear my Birks at Disney, and love them! I also went through the break-in period, unsure if I could wear them 15 minutes let alone a whole week or more of walking. But yes! One day, they became more comfy than my slippers!!! I now have a waterproof pair also, because when wet, my leather & cork ones became - uh- slimy to say the least! And the brown stain took days to rub off, and when walking it "splashed" up the back of my legs making it looked like some kind of Poo was running down my legs. My water proof ones are great though, I even wore them into my pool and walked around to see what the dryout was like. A little squeaky, but quick and painless. Try that with sneakers! This year I plan to wear my leather ones, but keep my lightweight water ones in my backpack to switch off to for wet rides or fountain splashing.
