I have heel spurs and have been wearing RX clogs for some time, but don't like their looseness or the way they look. The Santa Cruz RX are just as comfortable, and solve those problems. I really like the thick soft inner sole combined with the stiff outer, making for both cushioning and firmness. The only con for me is the lack of lateral support, which I notice and which would be worse for anyone who is pronated, I imagine. I wish Crocs would come up with an RX-soled shoe that has a more standard and supportive upper. Meanwhile, I will be wearing these all the time!
