Yes, it's just that it's a little cold wearing these thin dancing shoes on the cobblestones in this weather. You can buy a pair of foot health shoes with pebbles (to wear like slippers). I bought a pair in the summer. They are very fresh when I wear them in summer. When I took a few steps for the first time, I felt this. The soles of my feet were particularly sore, but this improved after some time of wear.
The wind enters through the back of the neck and the cold comes from the soles of the feet. Many diseases can therefore be improved through foot therapy, which includes foot bath, massage, etc.
Sweating while sleeping at night (because you didn't mention other symptoms, I can only roughly infer) is a sign of yin deficiency. If you feel hot, sweating easily is spontaneous sweating, which is qi deficiency. If you don't havez not hot, this is a sign of Qi deficiency. Involuntary sweating is considered night sweats. You can insist on soaking your feet in vinegar before bed to put out liver fire. Soaking your feet is the easiest way to replenish blood.
