Leading Safety Technology and Superior Comfort
FlexStep® – Grip and flexibility to work
The microporous FlexStep® sole material developed by Sievi maintains its excellent shock absorption and flexibility in freezing conditions. The footwear sole therefore remains softer, even in heavy freezing conditions, and maintains excellent friction on slippery surfaces. The construction of the FlexStep® flexible sole eliminates stress and shocks to the feet and spine, helping to prevent foot and back pains and thereby improving work efficiency. The FlexStep® flexible sole is featured on all Sievi footwear.
SieviAir® – Let your feet breathe
Developed and patented by Sievi, the SieviAir® sole solution takes care of your feet and improves footwear comfort. The SieviAir® system dissipates the perspiration from the shoe through special ducts in the side of the sole. Under the perforated insole there is a filter, which is connected to exhalation channels. With every step you take the filter is compressed, resuming its original shape when the foot is lifted. This movement produces a pumping action, improving the ventilation of the shoe. SieviAir® really allows your feet to breathe!
GripStep® – Unique friction sole
Sievi’s new GripStep® is the only sole structure on the market, where the friction properties of microporous po- lyurethane and TR rubber have been combined on the tread in order to maximise the grip. The sole grips firmly on cold and slippery surfaces. Thanks to the dual structure the sole is also flexible and shock absorbing. It feels comfortable from your first step.
DryStep® – Effective ventilation for your feet
The surface material of the DryStep® insole effectively transfers moisture away from the foot. The unique ventilation and pump action mechanism of DryStep® keep your feet dry and comfortable.
Dry feet with 3D-dry®
3D-dry lining, developed by Sievi, transfers moisture from the foot to the second layer of the lining and further through the upper and away from the shoe thus keeping your feet drier and more comfortable.
SieviBalance® – Safe steps and more grip
SieviBalance improves the rotational rigidity of the shoe and the control of the foot, reducing strain to the ankles and accident risk.
Sievi GORE-TEX® – Superior quality bringing more comfort
Everybody knows that the excellent breathability and water resistant properties of GORE-TEX® are second to none. GORE-TEX® lining is a unique material, which allows the feet to breathe but at the same time keeps moisture out.
Primaloft® – the best insulation in its category
The footwear is equipped with Primaloft® thermal insulation made with 90 per cent recycled materials. Waterproof, breathable and extremely light Primaloft® thermal insulation keeps your feet dry in any conditions.
BOA® Fit System – Fit to perform
Dial in your perfect fit for custom comfort that’s consistent all-day, the micro-adjustable Boa Fit System is fast, easy, and built to perform so you can always get the job done.
Sievi FlexEnergy – Flexibility at every step
The Sievi FlexEnergy is a flexible component integrated in the entire heel part of the shoe. With this component the shoe provides maximum shock absorption and excellent wearer comfort for long working days, regardless of the working environment. The component is made of BASF’s TPU Infinergy®, which is the first expanded thermoplastic polyurethane in the world.
Shock-absorbing heel – A light step day after day
The shock-absorbing heel area protects the feet and the skeletal system against stress. The product meets the requirements of EN ISO 20345:2011 and EN ISO 20347:2012: the shock absorption capacity of the footwear is at least 20 J. The cushioning effect is guaranteed by the use of FlexStep® sole material in all Sievi footwear.
Spike stud mechanism – Secure grip in challenging conditions
A stud mechanism integrated in the footwear sole construction enables you to turn the studs in and out when the weather conditions change, without the need to remove the shoes.
Thermo heating system – Maintains the work efficiency in the cold
Footwear equipped with the integrated Thermo heating system keeps your feet warm even in the most extreme conditions. The rechargeable heating system provides heat on a single charge for the whole working day.
