Travelling through Asia - Travel Shoes

I'm writing this still a little undecided about whether I'm packing too many or too few pairs of shoes for my trip, but I will share them anyway. Normally I live in flip flops in the summer and I find them comfortable enough to wear for most activities, but since we plan on doing a bunch of different activities on this trip, I've decided to bring a few more pairs.

I'm packing a pair or Birkenstocks, the Arizona's, this is my first time wearing Birkenstocks and so far they have been really comfortable (I'm working on breaking them in before I leave). Im also packing a pair of Nike Free running shoes, they are the most comfortble runner I've ever worn and they will be great for hiking and biking and exercising (if that happens :P ). The flip flops that I'm bringing are the Sanuk Yoga joy sandal (they are made from the same material as a yoga mat and are really comfortable). I'm bringing a pair of converse sneakers too for casual days, and a pair or simple leather sandals. I tried to keep them all pretty neutral so I can match them with almost anything...I may be crazy to bring white shoes, but they look better a little dirty anyway, right? ;)
