POLE STAR IS A RANGE OF HIGH QUALITY WINTER SAFETY BOOTS FOR EXTREME CLIMATE.

Those boots have been developed to withstand:
a) The hardest conditions of work (CE standard EN 344-345, S4-S5).
b) The most extreme climate conditions (up to –50°C).

Pole Star is made of:

1) CRYOFLEX® outer boot

• The material : thanks to the Gaston MILLE research this material has been tested to insure resistance and flexibility in very low temperature and to fulfill the conditions of the European standard EN 344-345 following S4 and S5,
• The design : for a maximum protection and comfort ; large arch support, reversed deep cleaned sole profile to give the best grip on ice and snow,
• A very large fitting toe-cap (extra large) to allow the best comfort and space for your feet including the 7 mm inner boot.
• Walkontan®: patented, this polyurethane innersole, thick of 5 mm, is embedded in CRYOFLEX® outer sole. It is a real cushion providing a very good insulation and softness. The Walkontan® also fills up the heel and provides a perfect “Shock Absorber”.
• Options: a Kevlar® antiperforation insole, a heating assistant system which is used as a first aid heating. In case of accident, a resistance placed under your toes and a battery incorporated in the heel, provides heating.

2) DRYTEX® removable inner boot

This inner boot is the combination of 5 different materials, which put together, ensures a very high thermal insulation. The performances of this inner boot has been proved and tested by the IFTH Laboratory in Lyon. The classification of thermal insulation can be compared with the highest standard of winter gloves available on the market (cat.4).
