CAMPER - Brown leather kids' 2-strap sandals with chrome-free leather-lined footbeds and 100% rubber outsoles. In 1988, Camper challenged the idea that shoes should be identical, designing a mismatched pair with asymmetric details — and their iconic TWINS was born. Outer material: 95% cowhide leather, 5% cowhide leather (80% cowhide leather, 20% polyurethane) Sole: 100% Rubber Better Leather.
