Foot odour is very common and happens when skin bacteria break down sweat. Since you already wear cotton socks, you can manage this with targeted over-the-counter options. For powders and sprays, look for those containing miconazole or clotrimazole; these keep feet dry and prevent fungal growth. To reduce sweating, you can apply an antiperspirant spray containing aluminium chloride to your soles at night. If you notice itching or peeling, apply a generic terbinafine cream. Remember to wash your feet daily with antibacterial soap, dry thoroughly between your toes, and let your shoes air out for 24 hours before wearing them again.
