The outstanding feature of the uvex 1 G2 safety shoe is its innovative sole, which uses the uvex i-PUREnrj PU sole technology. This technology not only offers high cushioning, but also reduces signs of fatigue in the wearer by channelling kinetic energy back out through the sole. The use of breathable materials, a seamless upper and a foamed heel basket further heighten wearing comfort, without significantly increasing the overall weight of the shoe.
