Here’s a quick science quiz for you:
Given that heat rises, what does cold do?
A. It also rises.
B. It luxuriates somewhere in the middle.
C. It falls.
Hopefully you didn’t need to consult a textbook for that one. But the point is that, as a matter of physics, this season’s ever-present chill is going to try to weasel its way into whatever part of you is closest to the ground. And since 97.2% of the time that’s going to be your feet, we believe an upgrade to their first line of defense is certainly in order.
