Bicarbonate of Soda for Smelly Feet: How to Reduce Foot Odour

Unpleasant foot odour can crop up even after a shower, especially when sweat, heat and closed shoes create the perfect breeding ground for bacteria. A familiar kitchen staple may help ease the problem: bicarbonate of soda, which is known for soaking up moisture and neutralising smells.

Why do feet start to smell?

Foot odour happens when bacteria on the skin feed on sweat and release strong-smelling compounds. Because feet contain a high number of sweat glands, the issue often gets worse on hot days, during exercise, or after wearing closed footwear for long periods.

Damp socks, poorly ventilated shoes and not drying properly between the toes all encourage these micro-organisms to multiply. That is why simply masking the smell is not enough. You also need to reduce moisture and adopt routines that keep both feet and footwear dry.

How does bicarbonate help with foot odour?

Used as a powder, bicarbonate of soda can absorb some of the moisture caused by sweating. It may also temporarily change the conditions in which bacteria thrive, helping to reduce odour in a practical way when combined with good hygiene.

According to dermatologist Ursula Metelmann, it can work as a natural option to absorb perspiration in certain situations. However, its effect does not replace medical treatment, and you should stop using it if you notice stinging, itching, redness or significant dryness.

How to make a bicarbonate foot soak

To prepare a foot soak, pour warm water into a clean basin and add about half a cup of bicarbonate of soda (around 120 ml). Soak your feet for 15 to 20 minutes. The water should not be too hot, particularly for anyone with reduced sensitivity in the area.

• Wash your feet before starting.
• Use warm water to help avoid burns and irritation.
• Dry carefully between the toes.
• Stop using it if you feel any discomfort.

This routine can leave your feet feeling fresher and more relaxed, but it does not need to be repeated several times a day. Overdoing it may affect the skin’s natural barrier and lead to irritation. Anyone with sores, cracks, diabetes or circulation problems should seek professional advice before trying it.

How to remove odour from shoes

Looking after your feet but ignoring your footwear can mean the smell returns quickly. One option is to sprinkle a small amount of bicarbonate of soda inside a dry shoe and leave it to work overnight. Before putting the shoes on, remove all the powder to avoid prolonged contact with the skin.

It also helps to rotate pairs, leave shoes in a well-ventilated place, and change socks every day. Very enclosed styles should be avoided whenever possible. Washing removable insoles and choosing socks that allow sweat to evaporate both support better moisture and odour control.

When does foot odour need attention?

Bicarbonate of soda may ease mild episodes, but ongoing odour can be linked to athlete’s foot, excessive sweating, infections or other skin changes. Flaking, cracks, blisters, pain, intense itching and changes to the nails are signs that deserve assessment by a dermatologist.

Do not wait until the discomfort affects your routine or confidence. Start with the simplest habits by keeping feet, socks and shoes clean and dry. If the smell persists even with these measures, seek medical advice to identify the cause and treat the problem properly.
