SAFETY SHOES SIEVI SIEVIAIR R2 ROLLER S1 SIZE 48

The SieviAir R2 Roller safety shoes are equipped with a composite toe cap. Breathability is ensured by Sievi's patented SieviAir® sole structure, which removes moisture from the feet through flow channels on the sole sides. 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® flexible element, a full-length flexible insert covering the entire sole area. It is made from BASF's TPU-Infinergy®, the world's first foamed thermoplastic polyurethane. This flexible element delivers maximum shock absorption and exceptional comfort, capturing the generated kinetic energy and returning over 55% of the energy back into each step. 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 that efficiently wicks moisture away from the foot's surface. The insole is microfiber. The ankle collar and tongue are padded. Foot fit is easily adjusted from the front using the BOA® Fit System closure mechanism. This mechanism makes wearing the shoes easy: by rotating the dial, you can securely adjust the shoe 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 base layer. The heel and forefoot feature PORON® shock-absorbing pads that dampen external impacts and reduce fatigue. The insoles can be hand washed. The shoes are antistatic, and their ESD properties prevent 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 SRC. Custom-certified orthopedic insoles, as specified by the manufacturer, can be fitted into this shoe while maintaining type approval.
