When I got there, the very nice hippie gentleman who waited on me showed me an identical pair to my old ones, priced at $80. OR, he said that he could refurbish my old Birkenstocks: recork, resole, whatever. And that would be $65. With the prices so similar, I asked him what the advantage to refurbishing would be. "Oh, well you could buy the new AND refurbish the old, and that way you'd have a pair just to kick around in."
Now, I may be Northwestern enough to have a good fleece, but do I really need "good" Birks and "kick-around" Birks?
