Comfort and sustainability go hand in hand in this model. Black Chelsea-style suede leather ankle boots. They feature a padded latex insole, rubber sole, and a sole made with natural fibers. The lining and insole have been tanned using a more sustainable process under the standards of the Leather Working Group (LWG). The yarn of the fabrics used in the lining is certified with the Global Recycle Standard (GRS) guarantee. A basic that never fails!
