*** IMPORTANT - FLESH WARNING - NOT FOR THE FEINT HEARTED ***
Rob Brydon is clearly an advocate for the long manly sock.
If you are of the same persuasion but feel this is not something you would like to purchase in public, then socksock has the answer. You can purchase from us in total privacy - we will not reveal your identity to anyone, and all socks will arrive in unmarked, discreet grey post bags to protect them from prying eyes and awkward explanations.
Our long sock suggestions include:
The Wigwam Base Camp Fusion Knee Length Sock (which we suspect was the actual sock Rob Brydon wore on QI on account of it being long and black, but also because it repels moisture, has merino wool softness and a cushiony sole.)
Or
The Wigwam Iron Man Long, Run Pro Knee Length - a lightweight white sock, which repels moisture and prevents blisters and includes a side vent, mesh breather panels to enhance air flow and a foot hugging fit which extends up the leg and over the calf for enhanced circulation.
But if you would prefer something a little more risque, take a look at these babies...
Flysafe socks
Commando Socks
Smartwool Ski Socks
Smartwool Snowboard Socks
They will all provide you with that long sock security you crave, whilst adding a little adventure to your sock wearing.
