The QS400 is a slip-on, laceless safety shoe. The removable footbed reduces strain when standing for many hours. The nonslip, metal-free, oil and petrol resistant outsole provides for energy absorption around the heel and is penetration-resistant. A 200-joule, scratch-resistant steel toe cap protects the forefoot. The upper is water-resistant (WRU) and offers antistatic protection. The shoe is certified in accordance with EN ISO 20345:2011 and meets the requirements of protection category S3.
