Well over 95 per cent of all leather processed by the shoe industry is tanned with chromium; this is also the case with the leather used by kybun. Chromium residue in itself is acceptable and non-toxic according to international norms and standards. Only chromium (IV) is regulated, and we abide by those regulations, of course: No traces of chromium (IV) are allowed.
For customers who are allergic to all chromates, we recommend the Halla, Sorak or Namsan models (men’s or women’s) in red. These three models are leather- and chromate-free.
