I have the most miserable time buying shoes...HOWEVER...I was pleasantly surprised by this shoe. It was a very little bit bigger than expected. I did order a large than normal size so I would think it probably runs very true to size where many many do NOT!! I normally wear a 10 EEE womens which for under $125 you about cannot find. Therefore, I buy a mens 9 EE or EEE depending on if it is a lace up or slipon as I have a high arch as well as wide feet. In an expensive dress shoe I wear a men's 8 1/2 EE or EEE again depending if it is a lace up or slipon. I believe I could have worn an 8 1/2 EEE in this shoe. I am impressed with the accuracy of sizing at this price. Its an excellent buy I only wish it came is other colors...black red blue or green. It impressed me to buy Propet shoes again or at least try them on. The price is really awesome as compared with similar shoes. Just hope they last as long as they are well fitting.
