Humidity means athlete's foot season.  If the skin between your toes is itching, peeling or cracking, you need an antifungal treatment.  Tolnaftate is the active ingredient in most athlete's foot treatments available over-the-counter (also effective against jock itch, ring worm, and some other fungal infections), so your choice should be driven by scent and price.  Avon Footworks Antifungal Foot Spray is a clear winner here:  It has a pleasant clean and fresh scent (unlike that horiffic smelling Desenex stuff my dad used to use) The 3.4 oz spray is on sale through July 15th — 2 for $6.99 or 3 for $8.99!  Use coupon code "FIRSTREP" for free shipping direct to your home or office.
