"2XU® Vectr Light Cushion Full Length Socks: These unisex running socks combine light cushioning with graduated compression to keep your feet comfortable and supported from warm-up through recovery. The X-LOCK system anchors your arch, ankle, and plantar fascia, preventing the sock from shifting inside your shoe during runs or workouts - a small detail that makes a real difference over longer distances. At 2.5mm, the cushioning layer absorbs impact underfoot without adding bulk, so the sock fits cleanly in daily trainers and low-profile shoes alike. The anatomical left-right design and seamless toe construction eliminate friction points that typically cause irritation during road running and tempo sessions.Built from 88% nylon and 12% lycra, these socks stay lightweight and form-fitting through repeated use. Zoned mesh ventilation increases airflow in high-heat areas to help keep your feet cooler, while Polygiene® odor control treatment provides lasting freshness without washing out. Graduated compression runs the full length of the sock, supporting your calf, shin, ankle, Achilles, and foot to help you warm up faster and recover more quickly after your effort.Why Our Fit Experts Love It""I wore these on a long run and noticed the X-LOCK system actually kept the sock from bunching around my arch - a small thing that makes a real difference over 10-plus miles.
