The Professional Sneaker That Works as Hard as You Do
The Birkenstock QO 400 Leather Regular Unisex brings sneaker style to serious professional environments. A fluid-resistant natural leather upper stands up to daily workplace demands. The outsole resists slip, oil, and petrol for confident footing on challenging surfaces. This shoe meets EN ISO 20347:2012 certification and O2 protection category requirements.
Birkenstock’s anatomical cork-latex footbed cushions every step inside the QO 400 Leather. It molds gradually to the shape of your foot over time. Weight distributes evenly from heel to toe throughout the day. That balanced support reduces fatigue through long shifts on hard floors.
Inside, a deep heel cup locks the foot into proper alignment. Built-in arch support stabilizes the foot with every step. Additionally, the integrated metatarsal pad lifts the transverse arch for natural forefoot relief. The regular width fits a broad range of foot shapes comfortably.
The slip-, oil-, and petrol-resistant rubber outsole grips confidently across wet and contaminated surfaces. The durable natural leather upper resists fluid penetration and holds up through heavy daily use. Together, these features deliver certified safety without sacrificing comfort. Built to perform every single shift.
The QO 400 Regular Unisex fits healthcare, hospitality, food service, and industrial settings naturally. Its slip-on sneaker silhouette also transitions easily into casual everyday wear. One shoe handles professional demands and off-the-clock comfort alike.
