one word - Birkenstock! I have been wearing 'Boston' which is a comfy clog, but they come in closed backs, too. A bit pricey, but I've had mine for over ten years! I have foot trouble - heel spurs to be exact - and my 'Birks' allow me to walk all day if I need to. Go to their website, or check on QVC.com - they sometimes have them at reduced prices. Beware of S-A-S!! Mine fell apart after I got them a little wet!!
