Racesox may be about technical attributes that any serious athlete would require, but we haven’t forgotten that each competitor has his/her own special preferences. The RX100 is designed for the athlete who prefers an ultra-lightweight sock so as to maximize the sole’s ability to grip the pedal or the track. Flat-knit construction throughout this sock coupled with TCK proDRI creates just enough of a layer between the foot and the shoe to provide comfort and transfer moisture away from the skin. And, there’s no cutting corners when it comes to durability.
