what is birko-flor
I did not (and now feel justified in drinking a glass of vino the next time I don my 10-year-old Birks). That is one of the fun facts I discovered while researching Birko-Flor, which was not around when I acquired my pair. According to the company, Birko-Flor is a fabric âmade of acrylic and polyamide felt fibers.â The good news: Itâs waterproof and cheaper than leather. The bad news: Acrylic is essentially a plastic.
