text: After several positive reviews, and Clarks good reputation, I bought them.I found them very uncomfortable. After only about 15 minutes of wearing, my ankles, knees, calves and shins began hurting. I think the arch support was not good for me. I couldn't wait to get them off. After removing them I had severe knee pain for a day. Needless to say, I returned them . Fortunately, I had no trouble or extra expense doing that.
