The Kangaroos Ultralite II Made In Germany uses a "10.1 OZ natural indigo dyed light weight 3/1 denim" from Kuroki (Japan / Okoyama). The upper is a combination of predominantly denim and suede as well as embossed cowhide. No expense has been spared with these shoes not only in the quality of materials but also the expert craftsmanship. This is highlighted by the secret pocket on the inside of tongue as well as the woven tongue patch that displays Kangaroos branding.
