Men's Composite Toe work boots and shoes are designed with protective Safety Toe Caps that are made of lightweight Non-Metallic Materials, such as; Alloy, Aluminum and Carbon Fibers.
Composite Toe Caps protect feet just as well as their thicker steel toe counterparts, because they must meet the same rigid work place safety standards set forth by the American Society for Testing and Materials (ASTM) for impact and compression.
And while Composite Toe Caps work hard to protect your feet from sharp or heavy crushing objects that might drop or roll onto the feet, they won't conduct heat or cold from outside elements like steel will.
One major advantage that Composite Toe Caps have over those made with steel is that they are are engineered to be much thinner, so they take up less room in the wall of the boot in the toe box area. This results in more wiggle room deep within the toe box of the work boots.
