The foot section includes a heel section, a toe section, a sole section, and an instep section. The instep includes a ventilation panel and a flex zone, each having a different stitch construction. The ventilation panel allows air to pass through the sock and the flex zone prevents bunching or wrinkling of the material against the skin of the foot.
