This foot powder can be used both directly on your feet, and inside your shoes. Putting the powder onto your feet helps them to sweat less, while the citrus scent helps any excess smell you may have. This helps to keep your feet cool, dry, and comfortable throughout the day. Simply pour a small amount of powder into your hand, and then rub it onto the foot. To put it in the shoes you can pour some into the shoe, then spread it over the sole. When I bought the powder in the lush store, the clerks also told me that T for Toes has an antifungal property. I have problems with bouts of athlete's foot, and using T for toes helps to both shorten the length of my outbreaks, and also seems to help prevent them from happening. It takes very little powder for each use, so a small cannister will last for a long time. This is a great, natural foot powder and antifungal treatment, that smells great.
