Toecap, com posite
Toecap made of composite
material is completely metal
free and fulfi lls the
requirements of the EN ISO
20345 standard. The toecap
insulates well against heat
and cold.
Penetration res istant
mids ole, com posite
The penetration resistance
fulfills the same EN ISO
20345 requirements as
traditional midsole made of
steel. Steel, however, gives
greater penetration
resistance, which is why
Sievi recommends a steel
midsole for the more
demanding conditions (e.g.
construction industry).
Resistance to oil and many
chem icals
Sievi’s sole resists oil and
many chemicals. The oil
resistance of Sievi footwear
meets the requirements of
the EN ISO 20345 standard.
Antistatic
Footwear designed with
antistatic features,
discharges the body’s static
electricity up to tolerances
of 100 kΩ - 1000 MΩ.
Water repellent
Sievi uses water-repellent
leather. Its water resistance
meets the requirements of
the EN ISO 20345 standard.
FlexStep® – Superior shock
absorption under the whole
foot
The FlexStep® sole
construction eliminates
stress and shocks to the
feet and spine, helping to
avoid the foot and back pain
that can reduce work
efficiency and quality of life.
FlexStep® sole is proven to
be a more comfortable and
safer way to eliminate
impacts.
Sole material PU/TPU
The double density sole
consists of polyurethane
and elastic thermoplastic
polyurethane. The outsole is
wear resistant and the mid-
layer is of shock absorbing
FlexStep® material.
ESD
Through its sole
construction, ESD footwear
provides a safe and
controlled method of
discharging the body’s
static electricity. The
tolerances for the resistance
of Sievi footwear are stricter
(100 kΩ-35 MΩ) than for
ordinary antistatic footwear
(IEC 61340-5-1).
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.
DUAL insole
The Sievi DUAL Comfort
insole has shock absorbing
cushions made of PORON®
material which aids comfort
to your feet and back.
BOA® Closure System –
more user comfort
Easy to use and durable,
the patented Boa® Closure
System signifi cantly
increases the wearer
comfort of the footwear. Turn
the button to achieve the
perfect fit.
