Footwear with an outsole or bottom that provides traction or grip on slick surfaces caused by oil, water or other chemical substances.
Technology found in certain boots and shoes that reduces the risk of static shock or build up in the individual wearer and the footwear itself. Optimal for electrical hazard work environments. Also referred to as “electrostatic dissipative.”
A metal guard constructed from steel that is located in the toe of the boot or shoe to protect from crush and impact injury.
Footwear constructed with an inner sock-lining along the footbed of the shoe.
A type of leather with a raised, napped finish. Often considered less durable yet softer than standard leather.
