I have been wearing birkenstocks for over half my life.  They are so comfortable, and have been very therapeutic for me since I was diagnosed with plantar fasciitis.  For that reason, I will never wear flip-flops again.  This shoe rivals a flip-flop in ease of wear--just slip them on and go.  They are also pretty durable, though I wouldn't wear them in the water.  There were some complaints that the shoe was uncomfortable, and I think if you aren't accustomed to Birkenstocks, these might be an adjustment.

I got the golden brown, and that describes the color perfectly.  I will likely pair these with summer shorts and casual sundresses.
