A new boot with integrated impact protection of the metatarsal part of the foot, using XRD® M-Guard. It is a high-tech material that is soft and flexible under normal conditions but hardens and absorbs up to 90% of the energy upon impact. For those in need of extra protection in demanding environments, this is an important function to decrease the risk for injuries to the upper foot. The shoes have a roomier fit for extra comfort, toe cap and nail penetration insert.
