Composite Safety Toe – Non-metallic toe exceeds impact and compression ASTM F2413-11 I/75 C/75 standards.
Puncture-Resistant Fabric – The Anti Perforation Textile Plate is lighter and more flexible than steel, with higher thermal insulation. Protects 100% of the plantar surface, and meets ASTM F2413-11 PR standards.
ASTM MT/75 Cofra Inter-Met internal metatarsal guard – provides metatarsal protection against impact, which protects the instep against the accidental fall of heavy objects.
Slip-Resistant Sole – Superb slip resistance thanks to the design of the outsole and to the closely located cleats, which guarantee grip both longways and horizontally.
Cut Resistant – Provides protection for users working with cutting materials and/or objects, such as glass and metal.
Polyurethane Insulating Value – The innovative Polyurethane compound of THERMIC, combined with an innovative manufacturing process, has resulted in a highly technological product that insulates against low temperatures and is lightweight thanks to the regular structure of its polyurethane cells.

Best boot constructionwise, fit, and function. So much better than muck boots, yet for the complaints. Awesome.
Posted by: Eric from Post Falls, Idaho
These boots are true to size. I've had the first pair for 7 months now and they still don't leak. Very comfortable and tough.

I wear these boots in mud and water everyday and I’ve never owned a boot that has performed better. The mud slides right off. The boots at light and supportive. They run a little big so definitely buy a size smaller. Very well made rubber boot.

All in all a 5 star boot for mining. Gave 4 because they aren’t well suited to operating equipment as they are fat, which sometimes interferes with foot pedal operation. Other than this top notch. My last pair lasted more than a year, even after outer layer of sole fell off. Spectacular performance!

I wear them in an underground coal mine. The light weight and insulation is unbelievable. I do a lot of walking in severe conditions ,mud,water,rocks,uneven terrain to name a few .The lugs are great for traction in this environment.Also having different colors to choose is a good option also.
