The Argon from Caterpillar is a work boot/work shoe hybrid that features a nylon shank with strobel and cement construction. There is a heel tab to assist in getting the shoe off and on. The upper is made of leather and the lining is a nylon mesh which allows for foot breathability. The midsole features PU mold cushioning for a more personal fit. The outsole is an SRX extreme slip resistant outsole that exceeds industry standards and greatly reduces the risk of slips and falls in the workplace.
