The success in sales is still continuing about two years after the official market launch of the RED LION line of U-POWER, the work shoe that restores energy at every step. This is a real innovation in the world of work footwear: thanks to the inclusion into the sole of BASF’S  INFINERGY insert, a material that has already been successfully used in running footwear, the shoes of the RED LION UPOWER line, in fact, return over 55% of energy at every step, guaranteeing maximum comfort and reactivity, with a relaxing effect from morning to evening.
