The original Aireator® was such a solid, versatile platform for a sock that it had to made in wool also. That is exactly what the Wooleator® is. Performance cycling and running shoes require a sock that doesn’t take up too much space. Cooler temperatures and inclement weather don’t mean your shoes grow to accomm0date thicker socks. You need better insulation in the same space. This is when the Wooleator® shines. Since they are so thin, they don’t take summers off. For an honest, fourseason multi-sport workhorse of a sock, try the Wooleator®.
