Treatment of house and shoes.

Treatment of house and shoes. Hello\! I am looking to know how to completely eradicate athlete's foot. It has been spread from my boyfriend to me and my son. We have carpet throughout the whole apartment. We also use the same tub sometimes. It's starting to stress me out. My boyfriend wears work boots that he leaves at work. I've heard of the apple cider vinegar soaks are effective. What are the ratios? 1 cup of vinegar to 3 cups of water? Is there hope to fully eradicate it with this approach?
