Leading Safety Technology and Superior Comfort
FlexStep® – Grip and exibility to work
The microporous FlexStep® sole material developed by Sievi maintains its excellent shock absorption and exibility 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® exible sole eliminates stress and shocks to the feet and spine, helping to prevent foot and back pains and thereby improving work ef ciency. The FlexStep® exible 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 lter, which is connected to exhalation channels. With every step you take the lter 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 rmly on cold and slippery surfaces. Thanks to the dual structure the sole is also exible and shock absorbing. It feels comfortable from your rst 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® keeps 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.
ThinsulateTM – First class thermal insulation
The footwear features thermally insulating and breathable ThinsulateTM bre. ThinsulateTM bres improve the thermal insulation by binding more air molecules between the body and the outside air.
BOA® Closure System – More user comfort
Easy to use and durable, the patented Boa® Closure System signi cantly increases the wearer comfort of the footwear. Turn the button to achieve the perfect t.
Sievi FlexEnergy – Flexibility at every step
The Sievi FlexEnergy is a exible 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 In nergy®, which is the rst 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 ef ciency 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.
