The Wooleator is a merino wool version of our
DeFeet's Famous Aireator sock . Cycling shoes require socks that don't take up much
space. Cooler temperatures and inclement weather don't mean your shoes
should have to grow to accommodate thicker socks. What you need is
better insulation in the same space. This is where Wooleator's shine!
