Why we built Treatonic
"Whoever walks in my shoes"
When my son was just over a year old, he invented his favorite game: stealing my shoes, sticking his tiny feet inside, and clomping around the house. The more I yelped "no, no, no!" the harder he giggled. He'd stumble, cry, pick himself up, and do it all over again. He wanted so badly to walk like a grown-up.
I laughed every time. And then, every time, I went quiet. Because I couldn't stop worrying about his feet.
I've had toenail fungus since high school. I've tried the creams, the lacquers, the home remedies. It would fade for a while. It always came back.
After years of trying everything with nothing to show for it, my husband and I dug into the research ourselves. We read case studies. We talked to podiatrists. One detail kept nagging at us: most antifungals are only active during the day, which leaves the fungus eight quiet hours every night to recover. So we built something that doesn't clock out at night. That's how our Day & Night System was born.
