Sievi’s new GripStep® is the only sole structure on the market, where the friction properties of microporous polyurethane and TR rubber have been combined on the tread in order to maximise the grip. The sole grips firmly on cold and slippery surfaces. Thanks to the dual structure the sole is also flexible and shock absorbing. It feels comfortable from your first step.
