– Ensures perfect fit with low volume construction, complete with reinforced microfiber toe and heel along with a unique Triple-Y heel design that creates a more formed, extra-deep heel pocket
– Keeps feet cool and dry with Balega’s proprietary Drynamix® moisture wicking fibers, plus specially constructed, reinforced microfiber mesh ventilation panels
– Maximizes comfort with hand-linked, seamless, reinforced toe, sensitive rib top, and high heel tab that helps prevent the sock from slipping into your shoe
