Steel toe boots (also known as safety toe boots, steel capped boots or safety boots) are durable boots or shoes that have a protective reinforcement in the toe, usually combined with a sole plate, which protect the foot from falling objects and punctures from below. Traditionally made of steel, the reinforcement can also be made of a composite material, or a plastic such as thermoplastic polyurethane (TPU). Steel toe boots are important in the construction industry and in many industrial settings. Occupational Air Jordan 12s safety and health legislation or insurance requirements may require the use of such boots in some settings, and may mandate certification of such boots and the display of such certification directly on the boots. However, the weight needed to induce such a failure would result in such severe damage to the toe that amputation would be necessary anyway.[1].

Some brands of steel toe footwear, particularly Dr. Martens and Grinders, have become fashionable within Air Jordan 2s subcultures such as skinhead, punk, and rivethead.

Most safety shoes have symbols on the outside, to indicate the protection the shoe offers. Examples are:Green Triangle indicates that it is a class 1 toe cap with puncture resistant sole. Yellow Triangle indicates that it is a class 2 toe cap with puncture resistant sole. White Square (with ohm symbol) indicates electrical protection. Yellow Square(with SD) indicates anti static protection. Red Square(with C) indicates electrically conductive. Fir Tree indicates protection against chain saws.

In the United States, the applicable standard for protective footwear is ASTM standards F 2412 05, Standard Test Methods for Jordan Retro 13 Foot Protection and ASTMF 2413 05, Standard Specification for Performance Requirements for Foot Protection.

OSHA requires compliance of ANSI Z41.1 1991, “American National Standard for Personal Protection Protective Footwear,” if purchased after July 5, 1994 [2].

If purchased before July 5, 1994, ANSI standard “USA Standard for Men’s Safety Toe Footwear,” Z41.1 1967 [3].

California has updated its regulations with the new 2005 ASTM standards F 2412 05, Standard Test Methods for Foot Protection and ASTM F 2413 05, Standard Specification for Performance Requirements for Foot Protection.

Generally, a safety shoe is a shoe that follows at least one of five criterion. You can determine which criteria your safety shoes adhere to by looking for CSA’s(Canada’s Standard Association) alphanumerical code found inside the shoe. This code is made up of a combination of Nike LeBron 12 5 different symbols: 1, 2 or 0 P or 0 M or 0 E, S or C X or 0

The first code indicates if the shoe has a steel toe cap(a metal shell embedded on top of the toes part of the shoe). “0” means there is none. “1” means that there is, and it resists an impact of 125 joules(22.7 kg object falling from 56 cm above). “2” means that it resists an impact of 90 joules.

The second code indicates if the shoe has soles that protect the arches of the feet from punctures. “P” means it does. “O” means it doesn’t.

The third code indicates if the shoe has a metatarsus protection against shocks and collisions. “M” means it does. “O” doesn’t.

The fourth code indicates the Nike LeBron 11 shoe’s electrical properties. “E” means it resists electrical shocks. “S” means it disperses static electrical. “C” means it conducts electricity.
