The Ultra was designed for the elite cyclist who prefers to wear a tighter fitting shoe for a more direct peddling sensation and thus requires the thinnest sock that technology permits. This seamless tube sock from Q36.5 is knitted using an ultra-fine, incredibly soft microfilament with smart fiber and a high elastane content ensuring a snug fit and zero crease interface with the shoe.

A new pattern construction offers strategic mesh panels for breathability and 3 multi-channel ribbed padding zones: one in the metatarsal area, one to protect the Achilles tendon and one at the instep of the foot.
