As we speak - mid May - I just came back from the EBC trek.
I tend to be very warm, except for easily getting cold feet and hands, due to bad circulation in my extremities (broke my wrist in an accident, and cold feet because of extended use of flippers for bodyboarding).
I used the light and medium versions of the Smartwool Crew socks, with the Hanwag Tatra GTX hiking boots. Socks are available in Amazon UK for example.
This combo kept my feet warm (very warm sometimes!), comfy, not smelly, and free of blisters throughout the trek - boots were partially broken in already. I must say the weather was very pleasant, sunny during the day at all days, and I only faced temperatures of -5C high up in the trek.
November is the start of the winter and it can get very cold (-20/-30C), especially higher up in the trail. It all depends on a few factors, such as your footwear, how you handle cold, etc. I would suggest you get at least one pair of Smartwool Heavy socks or equivalent, on top of other hiking socks you might already have. Better be safe than sorry. You really don't want to have to go down or suffer because your toes are freezing. You can use them day and night, and they're a great investment anwyay :)
