I have very sweaty foot. I'm wondering if there's any treatment for my condition or special socks and shoes that may help me cope with it?

Use Drysol. Drysol is an effective topical medication for sweaty feet.If your sweaty feet does not respond to topicals then Botox injections in the bottom of the foot can be beneficial.
Try natural. I would recommend soaking feet in Apple cider vinegar. It's good for sweaty and smelly feet.
