The Spirit collection not only looks good but also has built in features to meet the demands of today's workforce. Dual density cushioned soles featuring polyurethane and TPU components, plus poron inserts, full comfort insoles, and Bata's unique energy returning Tunnel System, provide exceptional under foot comfort. Latex toe cap linings, cushioned heel cups, and breathable linings to keep feet fresh and dry, lead to new levels of comfort in safety footwear. Every shoe and boot in the static collection is anti-static.
