Durability
Wool socks are durable and can withstand frequent washing and use. Wool fibers are naturally elastic and resistant to stretching and bending.  
Thermoregulation
Wool's natural crimp provides pockets of insulation that can hold and release heat.  
Moisture-wicking
Wool absorbs and wicks moisture away from the skin, keeping feet dry and comfortable. Wool can hold up to a third of its weight in moisture before feet feel damp.  
Odor resistance
Wool's natural antibacterial properties make it odor resistant. Wool wicks moisture away before odor-causing bacteria can form.  
Breathability
Wool is highly breathable, which helps prevent clammy or sweaty feet.  
Easy maintenance
Wool is self-cleaning and doesn't need to be washed after each wear. Wool clothing can often be cleaned by hanging it outside.  
Sustainability
Wool is 100% biodegradable and natural, making it an environmentally-friendly material.
