I am very disappoint with my purchase. I placed an online order with Sierra for the first time and will never shop with them again. I order a size pair of CROCS and the right shoe was smaller then the left shoe, both shoes are marked size 9, but they fit different. The left shoe fits fine and is roomy, the right shoe is fitted and my foot is hanging slightly off the shoe. I they are uncomfortable to walk in. I've had them for less then a week and cannot return them because they've been worn. VERY DISAPPOINTED.
