When it comes to widths, essentially there are 2 main groups of widths: generic wide and legitimately wide. E, EE, 2E, EEE, 3E, XX, 2X, XXX, and 3X all fit about the same. When it comes to Boots, Shoes, Socks, Slippers, and Sandals for men in generic wide, we have them at XLfeet in sizes 7-13, 14, 15, 16, 17, 18, 19, and 20, but they are more like a "gateway" width on the journey most of our customers take in their quest for legitimately wide mens footwear. If the wide boots, shoes socks slippers and sandals your finding in your local shoe store or othere websites isn't wide enough, this is the first sign you need to go wider and that your feet have graduated you to the next level of width. It's no coincidence that EEE - 3E Extra Wide is one of the most requested, yet at the same time most returned widths we sell at XLfeet. If even a sliver of this paragraph resonates with you, or makes you curious if 3E is wide enough, PLEASE CALL US! We can help guide you to the best fitting width and or size.
