Vertex Ultra-Light Cushion Running Socks have the sleek feel of a lightweight sock but still deliver cushioning just along the bottom of the foot. Plus they even have that handy lil’ tab on the back so they slip on easy. True Seamless construction reduces hotspots and blisters. Ultra high stitch count creates a super comfortable sock with a streamlined fit like no other. No slipping, no bunching, no blisters. Merino Wool makes this a fast drying and breathable “all-weather” sock that stays cool in the summer and warm in the winter. Antimicrobial merino wool repels bacteria and odor. Made in Vermont, USA.
