—01-02. Wool and leather.
I haven't come across the Birkenstock Basel before, but its simple mix of wool and leather looks rather nice, especially for the fall. The slip-on style is a nice alternative to the Boston, not that you really need one. The two-tone effect is rather nice, and unless you were able to score one of the exclusive Japanese models from Unionmade, there might not be a lot of options. They pair perfectly with some thick warm socks in the winter, and they combine well with denim or army trousers.
