A brand of sandals known for their distinctive sole-patterning and arch support. Popluar for comfort and practicality, they are worn in all walks of life, but have a special place in lesbian culture as the "official" footwear of dykes worldwide.
* Wearing birks does not make you a lesbian--they are after all just sandals. But if you feel like waving a flag, a pair never goes awry.
** Maitenance: Seal the cork with contact cement to prolong life. You can get them re-corked and re-soled for less than half the original cost, so they can concieveably last forever.
"Hey, sweet Birkenstocks (birks). When did you come out?"
