Haix safety shoe S3 Airpower XR3, 51 The Airpower XR3 offers all-round protection for the feet, as it is puncture-proof, waterproof, slip-resistant and impact-resistant. The hard-wearing outer leather (leather thickness 2.5 - 2.7 cm) consistently protects against sharp objects or sharp edges. The integrated steel sole offers even safer penetration protection against sharp objects compared to textile soles. The anatomically shaped, lightweight plastic protective toe cap fulfils the highest safety requirements, as it immediately returns to its original shape after impact and thus quickly releases the toes again. The shoes are permanently waterproof and extremely breathable. This is ensured by the three-layer Gore-Tex membrane in the entire inner lining. The shaft height is 16.0 cm. A leather reinforcement in the heel bend protects against friction. This prevents blisters from forming. The specially developed lasts guarantee maximum comfort all day long. Plastic toe cap.
