With 1 pair of wool cycling socks and the insulated booties - how low before the toes become an issue?
This varies from person to person and how thick of single wool sock you can get on without the shoe fitting too snug. In the cold it is more important for blood to circulate easily. Since your shoes are probably sized for warm weather I'm going to guess that you will only be able to wear one pair of thin wool socks and booties over the shoe.
Some people can be good with this down to 35 degrees for and hour or so but others would not be able to ride in this combo at much below 40-45 degree F for much over an hour.
The feet are the hardest thing to keep warm for most people. This is mainly due to the constant loss of bloodflow in the bottom of the foot while pedaling.
Booties generally work to some degree as long as its above feezing and the ride is not much over an hour.
This is a topic that has extensive discussion on some other threads and you need to be aware that for most cold weather cyclist's it is difficult to keep feet warm below 40 degrees F for any significant length of time without more significant measures. Do a search and read as much about this as you can.
