Every single pair of shoes is regularly checked at every stage of the production cycle. The Zamberlan family personally is constantly involved in the control of the production line. The extremely meticulous finishing department sorts out any shoes that do not meet the required standards. Tests and field trials are carried out. The Zamberlan family personally tries out new ideas and models: Emilio during his Sunday excursions and hikes. Marco during winter ice climbing, climbing, mountain tours and excursions in summer. Maria during her excursions with the "shouldered backpack".
