Breathable shoes only work with functional socks. Cotton socks retain moisture. Functional socks, on the other hand, wick moisture away from the foot to the outside. The next step is the breathable shoe membrane, effectively transporting the moisture out of the shoe. Therefore, the principle of breathable shoes only works with breathable socks. Only the combination of functional socks and breathable footwear effectively wicks sweat outward. This is how the principle of breathability can work.
