White Booties/Oversocks
You Can't go past white booties if you wanna be seen as a serious cyclist. They maybe unconventional and get dirty easily,but they sure do make you look good.
DeFeet make the best white oversocks I have ever come across.Mainly because they last alot longer and are factory made in the U.S.A and not out of some random factory in China or Pakistan!
