Sievi AIR R4 ROLLER S1P (sizes 39-48)

The Sievi Air R4 Roller S1P safety shoes deliver exceptional comfort and protection through innovative design features. These S1P rated safety shoes incorporate the BOA Fit System positioned at the side, which provides optimal pressure distribution to accommodate different foot shapes while ensuring a secure, customized fit.

The advanced FlexEnergy shock-absorbing heel component stores kinetic energy during movement and returns over 55% of that energy, reducing fatigue during extended wear. The proprietary SieviAir sole technology features specialized ducts integrated into the sole sides that effectively dissipate perspiration and heat, maintaining foot comfort throughout the workday.

The Sievi Air R4 Roller S1P construction includes an aluminum toe cap for lightweight protection and a steel perforation-resistant midsole for underfoot safety. The single density polyurethane sole provides durability and slip resistance, meeting SRC standards. The microfiber upper material offers breathability and flexibility while maintaining structural integrity.

These safety shoes comply with EN ISO 20345:2011 S1P SRC standards and are available in sizes 39 through 48, making them suitable for various workplace environments requiring reliable foot protection combined with superior comfort technology.
