These are very cute and seem well made. I really wanted to keep them but there were two nagging thoughts as to why I returned them. First, the sizing is different from my two other pairs of Spencos. I am a true 6.5, so usually I need to go up for most shoes. Because my other Spencos are 6, I stayed at that size, too small.
Secondly, as one reviewer had pointed out, they are very flat. Even though they have  wonderful comfortable cork soles, I feel my feet need more thick ness for the comfort they deserve with orthopedic sandals.
