These cutie-pie ankle socks are woven with luxurious combed cotton for softness, nylon for strength, and a touch of spandex for long-lasting fun. Blue Q uses "200 needle" stitch patterns, meaning there are 25% more loops and weave around the foot than most socks. 1% of the sale of these socks supports the humanitarian work of Doctors Without Borders / Médecins Sans Frontières (MSF).
