The Argyle Zip Safety Boot from Steel Blue Boots now participates in the American Diabetes Association Better Choices for Life program and is suitable for those with sensitive feet, needing additional comfort and protection. The Argyle Zip is a men's 6" derby style, lace-up ankle boot with an industrial grade side zip. The wider ErgoDefender steel toe cap allows the toes to sit in a relaxed natural position so there is no rubbing or pinching to avoid unwanted foot sores. The whole-body support of the Trisole technology, provides a vital foundation, while the supple leather allows feet to settle in with no break-in period.
