Safety class S1P
Shoes with a protective toe cap made of aluminum, plastic or steel. They are slip-resistant, antistatic and have energy absorption capacity in the heel area. They also have a puncture-resistant steel midsole and a closed heel area. A fuel-resistant sole is also possible.
Aluminum toe cap
Aluminum toe caps are approx. 40 % lighter than steel caps, but do not rust. They have very high stability and durability and are recyclable.
Slip resistance SRC
The shoe is slip-resistant both on ceramic tiles with NaLS (sodium sulphate solution) and on steel floors with glycerine.
Penetration protection/midsole steel
The penetration protection protects the foot from nails and other sharp objects. Steel midsoles are not affected by the shape of sharp objects or hazards. However, they only cover 85% of the tread surface. They are often used in the construction industry.
Exchangeable insole
The insole is not firmly integrated into the shoe, but only inserted loosely. It can therefore be easily replaced if necessary.
DGUV 112-191
This regulation stipulates that orthopaedic insoles may only be used in safety footwear in conjunction with a valid type examination. This is to ensure that specified and tested properties (e.g. antistatic properties) are maintained.
BOA® Fit System
The BOA® Fit System consists of three essential components: a finely adjustable twist lock, a lightweight yet extremely strong rope and low-friction rope guides. All BOA® Fit systems enable a precise fit quickly and effortlessly and come with the BOA® guarantee.
DUAL insole
3D-dry lining
Das von Sievi entwickelte 3D-dry-Futter leitet die Fußfeuchtigkeit vom Fuß zur zweiten und damit äußeren Schicht des Futtermaterials und weiter durch das Obermaterial aus dem Schuh ab.
FlexStep®
The FlexStep® outsole with micropores developed by Sievi preserves its excellent shock absorption and elasticity even in frosty conditions. The springy construction of the FlexStep® sole element protects the foot and spine from impact and excessive stress. All Sievi shoes have a FlexStep® sole.
FlexEnergy
The FLEXENERGY® suspension element made of the TPU Infinergy® material developed by BASF is integrated into the heel along the entire surface and ensures optimum shock absorption and perfect wearing comfort. The elastic interlayer returns more than 55% of the kinetic energy to your musculoskeletal system.
