Whether you're working outdoors or hiking through the pines, these all-season, midweight ladies crew socks thermoregulate to wrap your feet in steady comfort when temperatures change. They're knit from a Merino wool blend that dries quickly and moves excess heat and moisture away from feet. The performance fit means no slipping, bunching or blisters ... so you can focus on the task at hand, not your feet. One pair. Women's sizes: Small (4.5-7), Medium (7.5-9.5) and Large (10-11.5).
