The comfortable PINGU first walkers offer children's feet a high level of comfort on cold days. The insoles, which can be removed for ventilation, are designed to be warm. The upper material of the sportily designed boots is made of genuine suede. In addition, these winter shoes for boys and girls have a waterproof membrane that prevents moisture from entering. Since the unisex boots are each made with two rip tape fasteners, children can put on and take off these winter shoes independently.
