OnSteam® lining is also called technical leather, as it looks and feels like leather. It is a microfibre material that allows 6 times as much moisture transport as leather and is faster at absorbing moisture. The result is better comfort in footwear that feels dry. The material has an antibacterial effect and is sustainably certified. For diabetics, OnSteam® has the great advantage that it does not become stiff or crack like leather can do over time. OnSteam® is produced without impacting the CO2 balance.
