Leonardo Copper delivers the same all-season comfort and work-ready support as the original Leonardo, enhanced with RESISTEX® Copper technology for added protection and freshness:
-
Merino Wool: naturally regulates temperature, wicks moisture, and keeps feet dry in both warm and cold conditions.
-
RESISTEX® Copper infusion: helps fight bacteria, reduces odor buildup, and supports skin comfort during extended wear.
-
Cushioned sole: soft underfoot cushioning provides lasting comfort and impact absorption without adding bulk inside work or hiking boots.
-
Breathable zones: ventilated knit areas enhance airflow and speed up evaporation during long hours of wear.
-
Secure fit & arch support: reinforced heel and toe combined with arch stability help prevent slipping inside boots.
-
Seamless toe: reduces friction to help prevent irritation and blisters.
Built for work boots, trail wear, and long days on your feet, Leonardo Copper combines Merino Wool performance with copper-infused antimicrobial protection.
With moisture-wicking Merino fibers, copper technology, and seamless construction, these socks help maintain comfort during prolonged wear — without irritation, discomfort, or the usual adverse effects.
