These shoes are the most comfortable shoes I have owned. Period. They slip on and off very easily, especially with the loop in the back, yet they are not at all loose on my feet during the day. They have lasted incredibly well. I wore them from 2004 to 2012 - though admittedly I couldn't wear them to work over about two years of that. I have never before had a pair of shoes that, upon wearing out, left me liking them well enough that I knew I wanted exactly the same pair of shoes again.

The price here seems quite high at the moment, so shop around, hopefully the fact that they are gaining popularity isn't driving the price up that dramatically.
