These are the same ones we use on our authentic high-quality U.S. Army Roughout Boots, the Two-Buckle Combat Boots, and the US Marine and US Navy Boondockers and others. Made from 100% Virgin Rubber (not neopreme) and are the most comfortable wearing soles there are. They are One-size-Fits-All and will fit all U.S. Men’s sizes from 7 to 13. Just take them (along with our new heels if you like) to your local shoemaker and they will know what to do. This way your boots will continue to look like the original issues.
