SAFETY SHOE SIEVI AIR R4 ROLLER S1P SIZE 41 BLACK

The SieviAir R4 Roller safety shoes are equipped with an aluminum toe cap and a steel toe protection. Breathability is ensured by Sievi’s patented SieviAir® sole structure, which removes moisture from the feet through flow channels on the sides of the sole. While walking, the filter beneath the perforated insole compresses and returns to its original state, promoting ventilation of the footwear.

The sole material FlexStep® is polyurethane. It is a durable and flexible material providing excellent shock absorption. Enhanced flexibility during walking is provided by the Sievi FlexEnergy® flexibility element, a flexible pad covering the entire sole of the footwear. It is manufactured from BASF’s TPU-Infinergy® product, the world’s first foamed thermoplastic polyurethane. The flexibility element delivers maximum shock absorption and exceptional comfort. It absorbs the generated kinetic energy, with over 55% of the energy returned to the walking motion.

The upper is made of water-repellent and abrasion-resistant microfiber. The side features a mesh structure that enhances airflow. The inner lining is 3D-dry material, which efficiently wicks moisture away from the foot’s surface. The insole is microfiber. The ankle collar and heel are padded.

Foot fit is easily adjusted via the BOA® Fit System closure mechanism on the side. The mechanism makes wearing the shoes easy: by rotating the dial, you can securely adjust the shoes to the shape of your foot.

The removable Dual Comfort insole consists of three layers: a soft top layer, a breathable intermediate layer, and a lightweight, shock-absorbing EVA sole layer. The heel and forefoot feature PORON® shock-absorbing cushions that dampen external impacts and reduce fatigue. The insoles can be hand washed.

The footwear is antistatic, and the ESD feature prevents uncomfortable shocks caused by static electricity accumulated on the body. Available in sizes 35–48 with standard volume. CE-certified product. Protection class EN ISO 20345: S1 P SRC. Custom-certified orthopedic insoles, as specified by the manufacturer, can be fitted to this footwear while maintaining type approval.
