Safety-toe boots in the US are tested to ASTM F2413. The label lists the standard and each protection: I/75 and C/75 for impact and compression toe protection, Mt for metatarsal guards, EH for electrical hazard, PR for puncture resistance, SD for static dissipating and Cd for conductive footwear. Steel, composite and alloy toes can all meet the same rating; they differ in weight, bulk and conductivity.
A safety boot’s protection is printed inside the tongue or on a label. Here is how to read it.
The label
A typical label reads like ASTM F2413 M I/75 C/75 EH:
| Code | Meaning |
|---|---|
| M or F | Men’s or women’s |
| I/75 | Impact-resistant toe, 75 ft-lb test |
| C/75 | Compression-resistant toe, 2,500 lb test |
| Mt | Metatarsal protection |
| EH | Electrical hazard |
| PR | Puncture-resistant sole |
| SD | Static dissipating |
| Cd | Conductive |
Toe caps
| Steel | Composite | Alloy | |
|---|---|---|---|
| Weight | Heaviest | Light | Light |
| Profile | Thin | Bulkier | Thin |
| Conducts cold and heat | Yes | No | Yes |
| Metal detectors | Triggers | Does not | Triggers |
Choosing for the job
- General construction: I/75 C/75 with PR in areas with nails and debris.
- Electrical work: EH-rated boots, kept dry and in good repair.
- Heavy materials: add Mt protection.
- Electronics or flammable atmospheres: SD or conductive, per the hazard assessment.
Fit and comfort
Buy late in the day, in the socks you wear at work. A safety toe must not press on the toes. Lace-to-toe and wide fits help many workers.
Replacement
Replace boots after a significant impact or compression, when the sole is worn through or cut, or when EH or PR protection is compromised.
Pair boots with hard hats and hi-vis.

Common questions
Is steel toe safer than composite toe?
Both pass the same ASTM F2413 impact and compression tests when rated I/75 and C/75. Composite is lighter and does not conduct cold or heat; steel is thinner for the same protection.
What does EH mean on a work boot?
Electrical hazard: the sole is tested as a secondary source of protection against accidental contact with live circuits under dry conditions.
Do I need metatarsal guards?
Where heavy objects could fall on the top of the foot, such as handling steel, concrete forms or heavy materials. Your employer's hazard assessment decides.
What is the difference between SD and EH?
SD boots let static electricity drain away in a controlled way; EH boots resist current. A boot is rated for one or the other depending on the job.
