I moved to Chicago at the end of October from the deep south. The past few days the weather has been hovering around 0⁰F and that has been an adjustment. I've figured out the clothing I can wear to bear it. Sunday my feet felt like they were going to fall off after only a few minutes walking around. Last night I had to wait for a bus for like 20 minutes and I was totally fine. I switched boots and it fixed my whole issue with comfort.
