The Florsheim Fiesta features a black leather upper attached to a direct-inject, TPU outsole--both materials make this a great, all-purpose work shoe. Leather is naturally breathable, flexible and water resistant. TPU offers excellent abrasion resistance, is highly tensile (meaning it takes a lot of force to tear it) and remains flexible over a wide range of temperatures. In addition, TPU resists solvents, thus the soles are chemical and oil resistant. Overall, this means that soles made of TPU are long wearing, resist the degrading properties of heat, oil, chemicals and solvents, and are slip resistant. These casual oxford shoes have 100% non-metallic construction, and they still protect your feet. Composite toes are the non-metallic answer to steel toe protection. They're made of lightweight materials like Kevlar or plastic and meet ASTM standards. They're also Electrical Hazard Rated. Static dissipative (SD) footwear protects you from electrical hazards on the job. SD footwear has minimal electrical resistance. It won't promote the build up of static electricity, so sensitive machines are safer. Even if your shift has you working extremely long hours in these shoes, the XTR extra-large toe cap keeps your toes from feeling constricted and sore. They have a super-soft Polyurethane midsole and a removable Polyurethane cushioned insert to ensure that your feet stay comfortable. The Dri-Lex lining is designed to move perspiration away from your feet, keeping them dryer and healthier than many other types of shoes. Composit toe meets or exceeds te ASTM F2413-05 standard for protective footwear. This boot is 100% non-metallic and airport friendly. Material: Leather.
