SieviAir® – The Best Breathability for Your Feet
Developed and patented by Sievi, SieviAir® literally breathes with your feet, improving ventilation within the footwear with every step you take. Under the perforated insole there is a filter, which is connected to exhalation channels. At each downstep, the filter is slightly compressed before reforming to its original shape as the foot is lifted. With the help of this pumping mechanism, the exhalation channels in the sole construction dissipate the moisture generated by the warming of the feet, which guarantees the best breathability on the market.
