What Our Experts Are Saying: "The Feetures full cushion no-show running socks are the finest running sock I've used. They are made of full synthetic fibers, they help spread moisture over the surface of the socks. This keeps your feet dry and prevents blisters. Extra cushion in the heel and toes, thinner material on the top, and having no seam under the toes make them super comfortable. Add the high compression in the instep along with the friction pad under the arch help to prevent shifting in the shoe. They are my go-to long run sock." - Brian, Footwear Lead at DICK'S Sporting Goods Millbury, MA Fit & Design: Right and left toe design enhances fit, delivering maximum comfort and protection by helping to eliminate blisters Maximum cushioning and comfort that protects the foot No Show Tab height sits below the ankle for maximum versatility and blister protection Mesh construction on the top adds needed breathability Technology: iWick(R) fibers pull moisture away from feet to keep them cool and dry The Perfect Toe(R) technology makes sure there is no irritating toe seam to eliminate friction in the sensitive area Patented compressed arch support allows for more comfort Additional Details: Machine wash cold or warm, on the gentle cycle with a mild soap, avoiding bleach and fabric softeners.
