Two size charts are available. The one next to the size picker shows a size 10, which fits a 10.63 inch foot. Another table in the product description shows size 10, suitable for 11.33 inch feet. My foot is 10.5 inches. Inconsistency fills me with confidence! :(After reading reviews that "these shoes are larger than advertised", I decided to go with the smaller size chart. I also figured I'd order two pairs and return the ones that didn't fit best. I ordered one Size 9.5 and 10. Item arrived on time and was delivered as advertised.I first opened a size 9.5 and found they were about 1/2" too big.I thought I would order the pair in a size 10 return without opening the packaging, a day later I started thinking about a return also as a repeat order of size 9 as indicated in the table, I decided to open the shoes in size 10.5 and the difference in two pairs Shoes to compare.To my surprise they were the same size despite the fact that they were marked as 9.5 and 10.No difference other than the tag!Even though I wanted to order the size 9 listed in the chart I can't , since they are not for Choice is offered. And if I could they would probably send me shoes in the same size tag says size 9. lol I liked these shoes except for the fact that your exits ide exposed 2 fingers. I would be happier if the hole on the side was smaller. I didn't want to talk myself out of this purchase but they made it easy for me! I can't afford to spend $47 on shoes that don't fit me. I will return both pairs. This order is the 2nd and 3rd pair of shoes I've ordered from Revain that didn't fit me. I no longer order shoes online! Good luck buying these shoes is nonsense! Update: Waiting for a Revain order is like waiting for Santa. I love the wait so I tried to order the shoes again. This time from a different provider. Again the wait ended in disappointment. I'm so stubborn, four shoe orders and four returns. Buying shoes from Revain is a headache I don't need but I have no choice. How many shoes do I have to return before the rapture ends? Update: CAMEL SHOES emailed me. "Hi Kevin! Thank you for your feedback. Two products definitely. There is still 0.5 cm difference between the two sizes, which is as described on the product page. Due to the different measurement tools and conditions used, this difference will often overlooked. But in order to provide customers with a more accurate choice, we still want to specify this subtle size difference. So we write to you specifically to explain the details, and hope to get your understanding. Looking forward to your next update. Kind regards Regards, CAMEL Store SHOES", they claim that there is a 0.5 cm (3/8") difference between two pairs of shoes. Look at my photos and tell me my tape measure is lying! Also ... who makes shoe sizes with such tight tolerances 0.5 cm difference between size 9.5 and 10 wow I want to buy the perfect shoes!
