Sievi AIR R5H ROLLER S1P (sizes 35-38)

This breathable ankle boot offers comprehensive foot protection and advanced comfort features. Key safety elements include a penetration-resistant midsole for underfoot security and memory foam ankle protection, alongside a dedicated guard for the Achilles tendon. The innovative BOA® Fit System ensures a precise and secure fit. For enhanced comfort and energy efficiency, the FlexEnergy® component, recognized as the world's most advanced shock-absorbing heel, actively stores kinetic energy and delivers an impressive greater than 55% energy return, reducing fatigue over long periods. Further promoting foot comfort, the SieviAir® sole is engineered to actively dissipate perspiration generated by foot heat through specialized internal ducts, maintaining a drier environment within the boot. This model, also known as the sievi air r5h roller or sievi air r5h, meets the demanding EN ISO 20345:2022 S1P FO SC SR safety class, featuring an aluminium toecap for impact protection and a steel perforation-resistant midsole.

The BOA® lace length is 80 cm, available in sizes 35 to 38, with product code 44-52371-382-92M.
