I have tried SAS and Clark's which are OK but the best shoe I have found for comfort, support and style is NAOT. They are leather and come in many styles from sandles, flats, heels and boots. When we went to Hawaii several years ago I was by a specialty shoe store and went in to look for a comfortable sandle. The clerk showed me the NAOT and once I had them on I was in love. They are expensive $100+ but they will last you forever. I have 7 pairs in different styles and even the pairs with a heel (2") are so comfortable I can wear them all day even if I am on my feet. Another great thing is the insole is replaceable and you can make your shoes last forever. I just replaced insole on a pair of shoes I bought 4 yrs. ago and for $50 they are like new again. You really need to look for this brand and try a pair they are the best.
