Tingley’s natural rubber work overshoes stretch easily over the bulkiest of work shoes. With its reinforced heel and toe, these work overshoes are designed to stand up to tough daily wear. That's why they are considered the industry standard. Deep cleated outsole spits out debris for good slip resistance and longer wear. Heavy duty heel kick-off cleat for easy no hands removal. No lining for easy cleaning and decontamination. There is more material in heel, toe and sole for longer wear and less material in the upper which results in lighter weight and reduced leg fatigue.
