The KEEN x Gramicci JASPER ZIONIC combines performance and versatility. The rock-inspired, fast and lightweight sneaker now features even more climbing influences in a limited edition design developed in collaboration with outdoor lifestyle and climbing apparel brand Gramicci. Unique details such as zigzag stitching and lines reminiscent of mountain ridges pay tribute to Gramicci's traditional items. The use of hairy, rough suede emphasizes the nostalgic outdoor aesthetic. Like all KEEN shoes, the Jasper Zionic is deliberately made without chemicals. It is PFAS and antimicrobial free, and all leather is sourced from tanneries certified by the Leather Working Group for their environmental and social practices.
