That more than 20% of the world's population suffers from athlete's foot or has excessive foot perspiration
That the foot plantar surface has five times more sweat glands than its dorsal area, therefore breathable upper shoes are not at all a solution?
That puncturing the soles of your shoes and incorporating semi-permeable membranes or valves are not meaningful solutions because steam goes upwards and not downwards?
INNOVATION THROUGH RESHAPING
The ARIA technology is a new way of shaping insoles that, skillfully exploiting biomechanics and fluid dynamics, forces the hot and exhausted air under the foot to leave the shoe and be continuously replaced by new and fresh air from the outside environment.
