Warm feet start at the calves, warm fingers start at the core.
Arm warmers help the fingers stay warm. Tall wool socks, thermal full tights, and warm boots help the toes stay warm.
How much of each you need and at what temperature is what you need to sort out for yourself by trial and error.
Personally, a too warm shoe can be used with a less warm sock to adjust. Or with an extra warm sock and extra warm tights. Depending.
And generally I need less foot support for winter, as I'm seldom hammering at vo2 max... my lungs dont like sucking down that much cold dry air. Usually I'm more zone 2-3, with a little 4.
