Live probiotics
The effectiveness of Heidi's Best is proven by studies. In a three-stage study design, the probiotic foot spray was examined microbiologically, sensorially, and directly on humans. 95.2% of test subjects recorded a significant reduction in foot odor after a single application. Independently evaluated. Scientifically documented.

1
Wash your feet with warm water and mild soap to remove sweat and bacteria. Pay particular attention to the areas between your toes. Dry your feet thoroughly afterwards.

2
Spray the foot spray evenly over your entire feet – including the soles and between your toes – until it is completely used up. Hold the bottle about 10–15 cm away to ensure the spray is well distributed.

3
After applying the spray, give your feet a moment to absorb the moisture. Leave the product on without wiping or rubbing so that it can spread evenly on the skin.

4
Over the next few days and into the first week, the foot odor is gradually neutralized until it disappears completely. Once the microbiome is stable, the effect lasts for weeks or even months – for permanently fresh, carefree feet.

In short: Yes! Our probiotic foot spray has been developed so that a single application is enough to strengthen your skin's natural microbiome and sustainably displace odor-causing bacteria. Once the probiotic cultures are active, they stabilize the skin's environment and can neutralize foot odor for weeks to months.
Depending on your individual skin type, choice of footwear, and daily routine, a follow-up application after some time may be beneficial. However, the effect will last significantly longer for you than with conventional foot deodorants.
Heidi's Best doesn't just work superficially – it combats foot odor directly at its source . The probiotic formula uses "good" bacteria to sustainably suppress odor-causing microorganisms. This creates a healthy, balanced skin flora that prevents bad odors in the long term.
Unlike conventional sprays that merely cover up or dry out the skin, Heidi's Best offers:
In short: Heidi's Best is the most modern, natural and effective solution against foot odor – for everyone who wants permanently fresh, healthy and odor-free feet.
Yes – Heidi's Best is perfectly suited for sensitive skin. Our probiotic formula works particularly gently, strengthens the skin's natural flora, and is completely free of harsh fragrances, aluminum salts, or irritating chemicals. That's precisely why the product was dermatologically tested and awarded the top rating of "Very Good" .
For you, this means maximum effectiveness against foot odor with the highest skin compatibility. The mild, hypoallergenic ingredients support the skin barrier, soothe sensitive areas, and prevent dryness or irritation.
Heidi's Best is therefore the ideal choice for anyone looking for a strong, natural and at the same time extremely skin-friendly solution against foot odor.
Heidi's Best starts working immediately after application – the lactic acid bacteria it contains begin strengthening the natural skin microbiome and suppressing odor-causing bacteria. The effect builds up day by day , so foot odor is usually significantly reduced within a week .
What's special about it: After this initial phase, the effect lasts for several weeks to several months , depending on the individual intensity of foot odor – even with just a single application . The probiotic microorganisms ensure that the new, healthy balance on the skin remains stable in the long term.
In short:
Immediate activation, noticeable improvement within one week and an impressively long-lasting effect for weeks to months.
