After years of teaching, which I always do on my feet, these were the first things I ever found that didn't leave my feet aching at the end of the day. Unfortunately, I also do a lot of squatting to get at my students' eye level and that, apparently, causes the rigid soles of these to crack after less than a year. I'm on my second pair and have had the same problem after the same period in both pair. So, at $120 a pair, I simply can't afford to keep replacing these. I wish I could find something that feels this good on my feet, but that could actually stand up to the wear I put on them.
