Sievi’s new TractionPro sole

Sievi’s TractionPro is a new, rugged sole with grip, designed for cold conditions. Thanks to the TractionPro double-sole structure and material developed by Sievi,
the sole retains its excellent flexibility and grip properties in diverse conditions. The flexible upper layer of the sole is made of Sievi FlexStep polyurethane, which contains microscopic air bubbles that cover 40 percent of the material volume, ensuring excellent shock absorption – Sievi FlexStep shock absorption.

The dense bottom layer of the sole is made of durable TractionPro cold-resistant rubber, made up of two rubber compositions, which retains its flexibility and grip in subzero conditions. This rugged double-sole structure provides excellent cold insulation. The deep and sharp-edged sole profile guarantees maximum friction
and grip on different surfaces.

Complies with the SRC and HRO requirements of standard EN ISO 20345.
