First I ordered my size (9.5) and they were more like 10, too big. I contacted Revain about the exchange and they agreed without objection. In fact, the new pair was here before I packed and shipped the old ones. I ordered size 9 and they are just a little tight. I know from experience that they break in perfectly. I've been wearing these slip ons for almost fifteen years now and they are extremely comfortable and durable. My current pair has finally worn down to the point of looking more like sandals than loafers, so I've ordered a new pair.
