These are the same Light-Tread heels we use on our authentic U.S. Army Jump Boots. Made from 100% Virgin Rubber (not neopream) so they are the most comfortable heels made. They are One-Size-Fits-All and will fit all U.S. Men’s sizes from 7 to 13. Just take them to your local shoemaker and they will know what to do. This way your shoes and boots will continue to look like the original issues.
