Rule 28 Aero Socks

£24.99, rule28.com

Autumn equals hill climb season, which means marginal gains. Discarded bottle cages, chopped down bars, helmetless heads and aero kit are all part and parcel of this British tradition to the extent that most will even look at something as simple as socks for an advantage. British-based Rule 28 believes extensive wind-tunnel testing has proven its Aero Socks to be the fastest in the world at all speeds, even the slow ones I climb hills at.
