55% Acrylic, 23% Wool, 20% Polyester, 2% Spandex HIDE YOUR SOCKS AND SHOW OFF YOUR SHOES with these ultra-hidden footies. Short socks stay invisible in short boots and shoes, but keep feet warm with the perfect acrylic/wool blend built for comfort and durability. Unmatched insulating properties and resilience keep feet warm in a durable construction that keeps it shape wash after wash. EXPERIENCE MASSAGING CHANNELS that reduce surface-to-surface contact to limit abrasion, improve ventilation, disperse shock absorption and reduce fatigue. Visible furrows and ridges produce an accordion stretch that lessens the likelihood of blisters and allows the sock to move with the foot throughout repetitive stops, starts and impact. LOOK GREAT on long trips, walks, runs, shopping expeditions or extended days at the office with confidence in a sock built to move moisture and air to keep feet dry, comfortable and blister free. ENJOY REDUCED BUNCHING with a compression arch and mesh ventilation panels that diminish excess fabric and hold sock in place. No baggy heels or cramped toes. DON??T SWEAT with Dry IQ Technology that combines moisture moving fibers with unmatched ventilation for the coolest, free-flowing ride a sock can give. Get the feel of performance with socks built for your passion.
