Who says you can’t have it all? Our Vertex Ultra-Light Cushion has the sleek feel of a super stripped down, lightweight running sock but still delivers 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. Fine gauge Merino Wool makes this a fast drying and breathable “all-weather” sock that stays cool in the summer and warm in the winter. And since Merino Wool is naturally antimicrobial this sock repels bacteria and odor when you’re laying down the miles. Still made in Vermont. Guaranteed for life.
