As tools get lighter and faster, your boots shouldn't be an exception. The lightweight, athletically inspired Radical™ 452 GTX Steel Toe keeps pace with the guys setting it. Built of breathable mesh and tough Nubuc leather and supported by Danner's aggressive TERRA FORCE™ support system, it wears like a cross- trainer. But at no expense of safety as evidenced by a fully certified steel toe and the durability that has become Danner's calling card.
