Like wearing a second skin, our Raceday Aero socks are ultra-thin, lightweight, and offer a tangible aerodynamic edge for days when it counts the most.
Compared to standard socks, our Raceday Aero socks save you 2-3 watts tested at speeds of 25-28 mph. When you consider the cost per watt, these unassuming socks are mighty effective (for comparison, dropping $1k+ on a set of fancy carbon rims might save you a whopping 10-12 watts at the same speeds).
- Cuff: Vertically ribbed lycra fabric with a durable rear seam
- Foot: Highly breathable, ultralight nylon
- Silicon gripper inside top of the cuff
- Fully UCI legal

Washing & Care
Recommended for use on race day, not for everyday training. To ensure these socks serve you for a long time, please observe the following:
- Best washed by hand
- If machine washed, use delicate cycle and cool temps only
- Do not use fabric softeners or harsh detergents
- Hang dry only, do not put in the dryer
How to keep your aero socks from slipping down:
- Sizing: when in doubt, size down.
- Do not apply creams or lotions to your lower legs. Products such as sunscreen, embrocation, PR Lotion, or Lactigo will act as a lube and cause slipping.
- Minimize stretching the diameter of the socks while putting on / taking off -- Excessively stretched out socks will not stay up.
- Do pull the sock cuff far enough up your leg for the silicone gripper to do it's job gripping the thick part of your calf.
