Generally foot odor and athlete’s foot do not come from sweat, which surrounds your feet. It comes from bacteria on the skin, which is decomposed by the sweat. The waste product of this decomposition leaves a very unpleasant smell and is an ideal breeding climate for athlete’s foot and nail fungus.

The Zederna Insole is a 100% natural product from thin cedarwood. The back consists of a stabilizing cotton layer. The sole is flexible and adapts to your foot form after a few steps. It gives you a very comfortable feeling (even if you carry orthopedic inserts). Your feet can take a deep breath nearly as liberating as walking barefoot.
Here’s how Zederna Insoles work:
- The natural suction force of Zederna cedarwood absorbs the sweat effectively
- The Zederna Insole and its antibacterial effect work where foot odor and athlete’s foot develop
- Smell and fungus creating bacteria are eliminated

Here’s my take on the insoles. I wore a pair in my work shoes for months. My old insoles were a regular stock style and I used them because they were already in the shoes. I immediately liked the Zederna Insoles. I felt my feet were cooler and more comfortable. I liked the wood feel – my feet were not stuck to a fabric synthetic insole, but could move around on the cedarwood. Between my commute and work, I had my shoes on for 12 hours straight. The insoles were pleasant. They are perfect to use in your shoes after training.
Because they are thin, I think they could easily be used in running shoes or boots. I would wear them in training, and then, depending on the feel, I’d make the decision to wear then in a race or not.
