Puma safety shoe S3 Frontcourt Blue/Blk Mid, 43 The S3 safety shoe has flexible penetration protection with a non-slip outsole that is heat-resistant up to 300°C and impresses with optimum grip and perfect cushioning. A rotation point incorporated into the sole in the midfoot area minimises friction and signs of fatigue. Thanks to the special arch support, the Evercushion Relief footbed ensures optimum pressure relief and a natural position of the foot in the shoe. Shock-absorbing elements in the heel and forefoot area absorb shocks and impacts when the foot touches down, making the Frontcourt as comfortable as possible - even on long working days. Fibreglass toe cap and flexible FAP lite penetration protection. CE category II. EN ISO 20345:2011 ESD FO HRO SR.
