When making ours street shoes We attach great importance to quality and ecologically sustainable production. We only use vegetable-tanned leather (chrome-free) for our leather shoes. For our vegan collection we use cactus leather (leather alternative) or cotton in organic quality (kbA) - tested for harmful substances and allergy-friendly. The insole consists of a cover and a warm, sweat-absorbing felt sole. It is removable - this makes it easy to determine whether the shoe fits. The flexible TR rubber sole in the collection arches well over the toe of the shoe: This means that the toes are particularly well protected when running, jumping and running.
