The Light Runner is a low cut length sock that sits just above the collar without falling into the shoe. A thin profile prevents blisters and balances strategically-placed cushioning zones with the ‘custom-fit-feel’ of our patented knitting structures. Versatile comfort. Engineered for Whole Foot Comfort Knit with a fine gauge merino wool for temperature regulation and ultimate softness. Wicks moisture, dries fast, and resists odors. Free Range Toe Box ensures room for your toes while contouring around them. Deep Heel Pocket wraps the foot, holds in place, and prevents blisters. Narrow welt above the shoe keeps the sock from falling down. Material & Care Material Our materials are crafted to optimize odor resistance, durability, breathability, stretch, and moisture-wicking.
