Castelli Prologo 15 Lite Sock

The Castelli Elements 15 Sock cases your foot with a close-fitting sock that stays dry inside a cycling shoe. Stretchy fabric with midfoot support band keeps the sock in place. Reinforced heel and toe provide a sock that handles the duress of constant contact with a hard cycling shoe. The Element 15 sock lasts through multiple race seasons. Besides functional support, the Castelli logo on the cuff looks cool.
