IZA Effect Spray review vs PediSpray®: which works better?
Are you looking for IZA Effect to care for your feet or nails? If you also suffer from sweaty feet, foot odour or shoes that retain odours, you need to treat not only your skin but also your shoes.
PediSpray® helps to reduce excessive sweating on your feet. Sprinkle PediFris® Classic into your shoes to disinfect them whilst you’re wearing them. This tackles moisture, bacteria and fungi in the areas where they can keep coming back.
Disinfect your shoes and your feet
If you have athlete’s foot or fungal nail infections, simply looking after your feet is often not enough. Fungi can also linger in your socks, insoles and shoes. If you put on an untreated pair again, your feet may come into contact with those fungi once more.
Therefore, sprinkle PediFris® Classic into dry shoes before putting them on. Whilst you are wearing them, the powder disinfects both your shoes and your feet, reducing the chance of bacteria and fungi developing.
Less moisture, lower risk of recurring symptoms
Heat and moisture create a favourable environment for fungi in shoes. Use PediSpray® on clean, dry feet to reduce excessive sweating. This ensures less moisture remains on your feet and in your shoes.
Use Classic in all the shoes you wear regularly. This will keep your shoes hygienic and reduce the risk of athlete’s foot or fungal nail infections returning.
Three steps as an alternative to the IZA Effect
Don’t just treat your feet, but also the shoes you wear every day. This reduces the chance of bacteria and fungi returning.
Wash and dry your feet thoroughly
Wash your feet daily and dry them thoroughly, including between your toes. Then put on clean, dry socks.
Reduce excessive sweating on the skin
Use PediSpray® on clean, dry feet, preferably in the evening so that the spray can take effect. This helps to reduce perspiration and keeps your feet drier.
Disinfect your shoes with PediFris® Classic
Sprinkle PediFris® Classic into dry shoes before putting them on. Whilst you’re wearing them, the powder disinfects both your shoes and your feet. Treat all pairs you wear regularly and allow worn shoes to air out thoroughly.

Treat all the shoes you wear regularly
An untreated pair of shoes may continue to harbour bacteria and fungi. You should therefore also sprinkle PediFris® Classic into your work, sports and everyday shoes. This reduces the risk of symptoms returning when you switch between pairs.
When should you see your GP or a chiropodist?
In the event of pain, open sores, suspected athlete’s foot or nail fungus, diabetes, or extreme excessive sweating: seek medical advice. More:what to do about sweaty feet en Thuisarts.nl on excessive sweating.

Frequently asked questions about IZA Effect and PediFris
About “iza effect spray” and how it differs from Classic, combining products, and when to see a doctor.
Why is IZA Effect alone not enough for athlete’s foot and fungal nails?
IZA Effect is intended for foot and nail care, but does not treat the inside of your shoes. Fungi can remain there. If you put on an untreated pair again, your feet may come into contact with those fungi once more. You should therefore use PediFris® Classic in your dry shoes: the powder disinfects your shoes and works on your feet whilst you’re wearing them.
Why can fungal problems come back via your shoes?
Warm, damp shoes provide an environment in which fungi can persist. If you simply wash your feet but then put on the same untreated pair of shoes, your feet will come into contact with that environment again. That is why shoe hygiene is an essential part of looking after your feet.
Do you need to treat all your shoes if you have athlete’s foot or fungal nails?
Ideally, treat all the shoes you wear regularly, such as everyday shoes, work shoes, trainers and slippers. A single untreated pair can cause your feet to come into contact again with fungi that have remained in the shoe.
What else should you do besides treating your shoes?
Wash your feet daily and dry them thoroughly, including between your toes. Put on clean socks, change your shoes regularly and allow worn pairs to air out properly. This helps to minimise the amount of heat and moisture trapped in your shoes.
What helps if your feet also sweat a lot?
Use PediSpray® on clean, dry feet to reduce excessive sweating. Less sweat means less moisture on your feet and in your shoes. This creates less favourable conditions for bacteria and fungi.
Can you use PediSpray® and PediFris® Classic together?
Yes. You use PediSpray® on your feet to reduce excessive sweating. You sprinkle PediFris® Classic into dry shoes to disinfect them whilst wearing them. Together, they tackle both the skin and the shoe.
When should you get athlete’s foot or fungal nails checked?
Do you suffer from persistent itching, flaking, cracks, pain or discoloured and thickened nails? If so, have your feet assessed by your GP, podiatrist or chiropodist. Extra caution is important if you have diabetes, open wounds or a weakened immune system.
