   Baak Toe Protection Caps Four materials – always safe Toe protection caps for safety shoes must be able to resist an impact energy of 200 joules, independently of their material (pursuant to EN 20345:2011). 200 joules are achieved when a weight of 20 kg drops from a height of 1 metre. In another test, the toe protection caps must resist a static pressure of 1.5 tons (15 kilo newton). Baak uses toe protection caps made of four different materials: steel, aluminiun, composite and nano feverglas. The shape and design of the toe protection caps has a decisive effect on the space for the toes and the rolling of the foot. Cap materials Steel caps have always been used for safety shoes. They are stable, and their weight is less than 100 grams for size 42. Aluminium caps are 40% lighter than steel caps. Due to the weaker resistance of aluminium, they are a bit thicker than the steel ones in order to comply with the stability requirements of the standards. They are anti-magnetic. Composite caps consist of composite materials, which obtain the necessary stability from synthetic resins. They are also 40% lighter than steel caps, and their material thickness is higher than that of steel caps. They enable the production of completely metal-free safety shoes. Nano-fiberglass caps are a further development of common composite caps with an improved synthetic resin composition, which enables a higher stability of the caps and/or a lower material thickness and weight. Black is the typical colour of the metal-free caps. Cap shapes Symmetrical caps are used mainly for slim and normal-width feet. The instep of those feet runs relatively close to the centre towards the second toe, which is also the longest toe in most cases. Shoes with symmetrical caps have a sportive look. Asymmetrical caps are often used for relatively wide feet. The instep of those feet runs towards the big toe, which is also the longest toe in most cases. Shoes with asymmetrical caps provide more space in the area of the big toe. In addition, in the Baak two-width system, the asymmetrical cap for the extra-wi- de shoes is 8 mm wider than the symmetrical cap of the normal-width shoes. The BAAK® two-width system is used for the models of the Baak Industrial series with the BAAK® go&relax system (see page 41ff). Cap design BAAK® flex caps are extended on the outside. Thus, in combination with the BAAK® flex zone in the outsole, it is possible for the feet to bend naturally in the area of the basic toe joints. symetrical aluminium cap for width N (11) asymetrical aluminium cap for width XW (13) 8 mm wider Different toe caps for different shoe widths                                                                                Baak flex zone natural bending line Functional foot load thanks to the BAAK® flex cap and BAAK® flex zone              PPP P P            97     l l l l f f k k p p a a a a c c x x a a e e B B f k e l x a c a a BAAK Know-How p B
