Is it normal to sweat under your feet?
Yep.Totally normal
Yes. The soles of your feet have plenty of sweat glands, so sweating there—especially in warm shoes, during exercise, or when you’re stressed—is normal.
Your feet are meant to sweat, even if socks and shoes make it feel extra noticeable. How much varies from person to person, and a bit of dampness is nothing unusual.
Breathable shoes and socks can help if it bothers you. If your feet are soaking through regularly or the sweating is getting in the way of daily life, it may be worth asking a healthcare professional about it.
