Sizing is easy. Use the formula and chart below to translate your standard size.
Length: -1 from usual size ( -2.5 for womens)
Width: choose preference
C - Extra narrow
E - Narrow
3E - Regular
5E - Wide
*Brannock device - if you get sized via a brannock device, make sure you are in a seated relaxed position and not standing on the brannock. (This accounts for the natural curvature of the arch support inside the boots.)
