I initally loved these sandals known as Telic/Terox- over time bought 6 pairs! and bought my husband some also...wore them in all colors with outfits--then we both started developing knee pain, and attributed it to many other things- until we discovered we both were wearing the same sandals<br />and a podiatrist said the sandal looked as if it had support- but the cushy-ness negated all support.  Went back to my Dansko and Abeo sandals and all knee pain has vanished.
