I got my current pair on sale a couple of years ago and they are not dead yet (although fairly light use), but this year they didn't have any in stock of more than six styles I checked within hours of the sale announcement. I emailed them and they said they had been out for months. So sleazy advertising and expensive and most of the styles look horrible IMO (and, as the article complains, any style you like will no longer be made once you need another pair), but good shoes.

I'll keep an eye out for the cloth shoes. Not many options for thin sole shoes. Concrete can be horrible on shoes with softer soles, however, and the Vivobarefoot soles are the best thin soles I've seen for use on concrete.
