Recently ordered a pair of Low 1s (canvas). I typically wear a size 8.5. The OC website and reviews mentioned the shoes ran large and to size down. So I did. I am typically an 8.5 US so I sized down to an 8. I received my order quickly but.... they were too small. I needed to exchange for a larger size. Very rarely... do returns go smoothly when ordering on line but I was VERY impressed on how easy it was to return/exchange my order. In my shipment notification there was a link to start a return. Once initiated, I was automatically sent a shipping label to return the shoes. I dropped off the shoes at the post office and by the time I got home.... I had a message that my replacement shoes were on the way. Amazing customer service. OC stands behind their product. New shoes in size 9 arrived a few days later and are a perfect fit. Love the way these shoes look and wear. If you are considering ordering a pair but concerned about return/exchange.... OC has this figured out. Great experience and great shoes. 5 Star !!!
