The average shoe size for a man is 10 to 12. This explains why many military boot manufacturers only make boots up to size 14.

And you know what big feet mean? Even bigger problems while boot shopping.

Basketball star Shaquille O’Neal wears a size 23. And if he’s shopping for combat boots, unfortunately he’ll have to go the custom route. But if you wear a size 17, you’re in luck.

Magnum makes a military boot that goes up to a size 17 regular. The Magnum Stealth Force ($99.95) is a black soft-toe boot. With full-grain leather and a ballistic nylon upper, the side-zipper boot is large and in charge. Along with a Cambrelle moisture-wicking lining and Agion antibacterial treatment, the compression-molded EVA midsole creates a comfortable wear for men and women.

If you’re a size smaller, look no further than the Men’s Belleville 300 DES ($111.99).

The tan steel-toe boot has Vangaurd running sole construction. The upper material is a full-grain tan cowhide; the outsole is Vibram. Don’t forget the Polyurethane removable inserts—a very nice touch indeed. This boot is available in a size 16 regular and wide.

And then there’s the world’s largest boot…

Even Shaq himself would look puny next to this gargantuan tower of boot. Erected by Red Wing Shoes, the work boot is a size 638 and a half. It weighs in at an astounding 2,300 pounds. To fit into this boot, you’d need to be 12 stories tall. Ready to test it out?
