Athlete’s foot is one of gym-goers’ biggest fears, and on top of the discomfort, the fungus can also contribute to foot odor. Moisture between the toes will itch for a lot of people. Thinking it must be fungus; those exercisers will apply an anti-fungal cream, hoping to nip things in the bud. Instead, the moisture from the cream just makes things worse. Save the cream for just the bottoms and sides of your feet, and opt for anti-fungal powder between the toes.
