Theres only one colour scheme for a secret-weapon sock if a sensitive and particular pro wants to wear it without breaking a sponsorship contract: all white, no markings. Without giving too much away this sock (in its original version) is all white and has no markings. Originally designed for the elite cyclist who prefers to wear a tighter fitting shoe for more direct pedalling sensations and thus requires the thinnest sock that technology permits. This seamless tube sock is knitted using an ultra-fine, incredibly soft, microfilament with high elastane content for a snug fit and zero-crease interface with the shoe. It is designed with strategic mesh panels for breathability and 2 multi-channel ribbed padding zones, one in the metatarsal area, the other to protect the Achilles tendon. Youll barely notice youre wearing it.
