Help me with my horrible problem? :(?

It's just that you sweat a lot when you are wearing shoes. Get a foot powder to dry the moisture in your shoes while you are wearing them. Get the kind that you can sprinkle onto your feet, and have showers regularly. Also, remember to wash and dry your shoes sometimes. Wash in the clothes washer, if the shoes are cloth. If the shoes are leather do not wash but polish from time to time to keep fresh. As for your feet, keep them dry and wear shoes that allow air to circulate around your feet as you are prone to moisture. Hope that helped
