Manu Metallic is made of nylon and the inner reinforcement consists of 50% polyester from plastic bottles. In the insole, you will find a soft layer of the foam material EVA, which is both lightweight and shock-absorbing, lined with the characteristic WODEN cork, ensuring breathability. Our children's styles are always equipped with a growth allowance on the insole, so you can be sure of your child's correct size. Our outsole consists of 65% natural rubber, 10% rubber, and 25% conventionally produced rubber. This guarantees your child stability and durability.
