So, my trusty and well-worn pair of Birkenstocks fell apart on me while I was walking in them. Luckliy the shoe-shiners have shoe repair knowledge and supplies. This guy stitched the two parts back together. THEY LIVE ON! For $4.
Also, it is a warming feeling to know that the shoes I was walking in were sewn together by hand. Every time I looked down I saw the stitches and it was as though I was carrying a part of another person with me.
