Sievi Alaska Roller + S3 boots have an aluminum safety toe cap and steel nail penetration protection. The shoe has the world's most advanced heel cushioning, based on the Sievi FlexEnergy® elastic element. The FlexEnergy material also insulates well from the cold, which brings additional comfort to winter footwear. The Sievi TractionPro friction sole ensures excellent grip even on slippery surfaces. The dual structure of the sole and the nitrile rubber compound provide excellent flexibility and grip properties even in varying and demanding conditions. The upper flexible layer made of TractionPro's FlexStep® polyurethane maintains its flexibility even in severe frosts, and in addition, the air bubbles in its structure provide excellent shock absorption. The sharp-edged profile of the sole is designed to maximize friction and maintain grip. The sole is resistant to oil and several chemicals.
The shoes are equipped with an easy-to-use Boa® Fit System fastening mechanism. The footwear is quick and easy to take off: the lacing is released effortlessly by lifting the roller. The ankle is supported by a Memory Foam ankle protector that follows the user's foot and absorbs impacts to the ankle. ESD approved. Note! Delivery time for shoes is 3-5 days.
