I found they run a little small but not excessively like some other brands, maybe order half a size up? However I will caution they have a wide toe box and my heel slips. I have narrow feet and high arches, use Specialized Riatas for mountain biking. Specialized makes a high quality shoe and are acceptable for my purpose but if you are replacing a problem pair you might want to try them on first.
