AIR 8000
Maximum Breathability
It is essential that the upper can breathe to keep feet comfortable inside mountain footwear. AIR 8000® is AKU's exclusive fabric system that lets heat and moisture escape — so your feet stay cool, dry, and blister-free.
What is AIR 8000?
AIR 8000® is an AKU exclusive system that ensures our footwear has the highest level of breathability. It consists of a specially made fabric whose breathability increases over a period of 24 hours, reaching up to 11.5 times more breathable than a conventionally made fabric.
