Blue Tongue Station Boots have TPU non-marking soles and are oil-, acid- and slip-resistant. A woven LENZI footbed provides puncture protection from foreign objects, and allows for far more flexiblity than a steel plate without transmitting heat or cold. The spring back polyurethane mid-sole and EVA removable insole combine to provide maximum comfort when spending long work days on your feet. The optional Composite Safety Toe is lighter than the steel toe cap while meeting the same ANSI/ASTM safety requirements. Available in sizes 7-13 US.
