Used to reduce foot moisture, friction, and odor in situations where hygiene is limited and foot care is essential—such as during long hikes, shelter stays, or off-grid living.
Sodium bicarbonate (baking soda) neutralizes odor and sweat acidity, while cornstarch absorbs moisture to reduce friction and help prevent blisters. Combined, they create an effective, shelf-stable foot powder that supports comfort and cleanliness without relying on commercial products.
