Keep those ticks and mosquitoes at bay with the ultimate insect-deterring hiking sock featuring BugsAway® protection. Engineered with built-in arch support and a seamless toe closure, these socks provide dependable comfort on the trail or on the run. Knit from a breathable wool/nylon blend yarn, with spandex throughout for extra retention, they wick moisture away from your skin to keep your feet dry and warm. BugsAway® product is treated with Insect Shield®, giving you invisible, odorless protection. The treatment binds permethrin to fabric fibers for the life of the garment, so it stays in your clothes—not on your skin—and lasts through 70 washes. It's effective against ants, flies, chiggers, midges, and ticks, as well as mosquitoes, which can transmit insect-borne diseases such as Zika, Chikungunya, Dengue, and West Nile viruses.
