Query: Birkenstocks do NOT live up to the "hype"...

These are my first Birkenstocks I own, I have bought the "knock-off" brand before and been halfway successful....my judgement: I'd rather spend $10 on fakes, than $40+++ on these real ones. They are NOT as comfortable as I had heard, nor are they any nicer than the fakes. Big waste of money. The only thing I liked was the silver color they came in...
