Safety boots with Metatarsal protection

MACCROSSROAD 3.0 S3 HIGH META

When to use metatarsal protection

In traditional safety footwear, the toes are protected by a 200-J toe cap, however, the metatarsals - the long bones connecting the back of the foot (the tarsus) and the toes (the phalanges) - are left unprotected. For trades where there is a risk of heavy objects falling, it's not only your toes that are exposed to potential impact, the top of your feet are too. It's therefore recommended that workers wear safety shoes that incorporate metatarsal protection.

In EN ISO 20345, the additional requirement M states that a safety shoe must feature metatarsal protection that is resistant to 100 joules of impact, equivalent to a weight of 20 kg falling from a height of 50 cm.

A safety shoe with metatarsal protection is key for any trade where there is a risk of heavy objects falling. Traditional solutions offering metatarsal protection have a metal plate to protect the metatarsal area, which limits flexibility and makes the safety shoes heavy.

Featuring D3O® technology, the Heckel MACCROSSROAD 3.0 S3 HIGH META safety boot ensures optimal protection against falling objects, particularly for those working in the construction and public works sectors or in heavy industry.

D3O® Metatarsal protection

D3O® uses patented and exclusive technologies made from non-Newtonian fluid to manufacture flexible materials with impact absorption. D3O® offers an ergonomic solution guaranteeing safe metatarsal protection (M additional requirement according to EN ISO 20345 standard) against impacts, without restricting movement and ensuring high levels of comfort.

D3O® technology

Used worldwide by the military, professional athletes and industrial workers, patented D3O® technology makes it possible to manufacture soft, flexible materials with high shock absorption properties.

The ultra flexible material moulds to the shape of the foot, giving the wearer complete freedom of movement while the light weight design does not contribute to the overall weight of the safety shoe.

How does D3O® technology work?

D3O® is a flexible, cellular material made of "floating" molecules. In its raw state, the material is very flexible. However, upon impact, these molecules have the capacity to bind together and instantly (in less than 10 milliseconds) transform into a solid to absorb and dissipates the generated energy. This reaction is not only immediate but also proportional to the force of impact. The greater the impact, the more the molecules will react, providing the best possible protection. After the impact, the molecules will return to their free-flowing state.
