Wool is a staple of the DeFeet line. DeFeet source the highest grade wools and combined with DeFeet construction the result is the finest wool sock that you can buy.
Wool socks stay cooler in the heat because of the construction of the mesh, warmer when they are wet and in cooler temperatures because of the thermal properties of merino wool.
Woolie Boolie 2 has new features over gen 1 that include, a padded terry loop top cuff, foot sole and arch compression in foot for greater stabilisation.
