Florsheim's men's Composite Toe SD Lace-Up shoes are the working man's Oxford. Made with Full-Grain leather, the uppers of these shoes are durable and abrasion-resistant for extra oomph with every step you take. The long-wearing polyurethane outsole is oil- and slip-resistant, which means you'll stay steadier on your feet and your shoes will stay stronger even on the harshest working terrain. An ASTM-approved composite toe will keep your feet safe from damaging impact without setting off the metal detectors. Thanks to the static dissipative feature of these oxfords, you can shuffle across shag carpet and touch your laptop without worrying about sending shock waves through your index finger. Let's talk about the inside of these Florsheims. A Tailex and Cambrelle lining will keep your feet cool and dry no matter how much you sweat. Florsheim's 3D polyurethane midsole helps soften the impact of cement floors. The removable F2A dual-density cushion insert is made with shock-absorbing polyurethane which helps absorb shock. Composit toe meets or exceeds te ASTM F2413-05 standard for protective footwear. This boot is 100% non-metallic and airport friendly. Material: Leather.
