alu-tec® technology: The New Lightness. Aluminium has not only served as a high-tech material in the aviation and automotive industries for years, it is also used today in many ATLAS safety shoes. The anatomically shaped toe cap made of aluminium is particularly light and shifts the shoe's centre of gravity towards the middle of the foot. This actively works to avoid accidents caused by stumbling due to a loss of balance. The thermally neutral behaviour of aluminium also prevents cold bridges from forming inside the shoe and thus guarantees a pleasant foot climate in all seasons.
