What Our Gearhead(R) Experts Are Saying:"Left/right specific fit is one of those details that sounds minor until you've worn a sock that actually conforms to your foot. Pair that with targeted toe cushioning and Climacool wicking and these hold up well on longer efforts when foot comfort starts to matter."Foot comfort tends to go unnoticed until it isn't. The Adidas Run Light Crew Sock is built to stay out of your way, with a superlite construction that keeps weight off your feet and Climacool technology that moves moisture out before it turns into friction or heat. Left/right specific shaping means the sock sits where it's supposed to from the start, and targeted toe cushioning adds just enough protection where impact accumulates.
