How to stop sweaty feet in sandals
You put on sandals because your feet need air. And yet: after an afternoon in the sun, the insole feels clammy, and sometimes the pair starts to smell sooner than your shoes do in winter. Open footwear helps, but the material of the insole and how much you sweat on your skin determine how fresh you really stay.
Changing, airing and allowing the skin to breathe help, but PediSpray® Walking barefoot is the most natural step.PediFris® Classic only if the powder remains in place, for example in a sock.
Open sandals, yet still clammy feet
You choose sandals precisely because they are ‘open’. Yet, after a hot afternoon, the footbed often feels sticky, and the pair starts to smell sooner than you’d expect. Not because open shoes are useless, but because ventilation alone isn’t enough.
Synthetic insoles trap heat and moisture; leather or cork absorb moisture better and release it later. When barefoot, sun exposure and friction are added to the mix. Fresh sweat has hardly any odour. The odour only develops when bacteria on the skin and in the sole break down that moisture.
And that is precisely where the pitfall lies: even a sandal with a fine, breathable footbed will not deactivate your sweat glands. If you want consistently drier feet, you must also inhibit sweating on the skin, not just rely on more air holes.
What you can do to combat sweaty feet in sandals
Shoe shops are right to recommend better materials and changing pairs of shoes. That helps. But on days when your feet get sweaty, during long walks or if you naturally have sweaty feet, the skin remains the source of the problem. That’s why the order is: first, reduce sweating; then, ensure a clean footbed; and use powder only if it really stays in place.
Reduce sweating on the skin
Apply PediSpray® (Regular or Strong) in the morning to clean, dry feet and allow it to be absorbed. Unlike a foot deodorant, which mainly masks odour, this antiperspirant reduces sweat production. This is particularly valuable when wearing open sandals: you often walk without socks, so your skin is your only ‘buffer’.
Remove bacteria from the sole of the foot
After a hot day, the footbed becomes a breeding ground for bacteria. Wipe or rinse the straps and sole (follow the manufacturer’s advice), allow the sandals to air out and dry them thoroughly before wearing them again. On long days, alternate between two pairs: this prevents moisture from becoming trapped.
Powder only where it remains in place
PediFris® Classic is intended for use where it comes into contact with the skin or lining. In open sandals worn barefoot, loose powder will fall out. If you are wearing socks: sprinkle it into the sock. Without socks: avoid using powder and stick to the spray plus cleaning.

Fresh feet start with the skin, not just in the shop
A better footbed helps wick away moisture. PediSpray® ensures that less moisture builds up in the first place. Together, they make a summer’s day in sandals feel much more comfortable.
Materials, hygiene and habits that make all the difference
When making a purchase, a breathable footbed helps: leather or cork often feels drier on hot days than smooth synthetic material. An open sandal with a synthetic footbed can feel surprisingly clammy, whilst a more closed-toe style with a good leather footbed is actually quite comfortable. PediFris does not sell sandals; however, it does help to understand why ‘open’ is no guarantee.
Your routine will then determine how much odour returns. Dry your feet thoroughly, including between the toes, before putting on sandals. Do not store a damp pair in a bag. Wash the footbed and straps with lukewarm water and mild soap if they feel sticky or dirty, and allow them plenty of time to dry thoroughly. When travelling or during a heatwave, a second pair is not a luxury, but a way to prevent bacteria from thriving.
Home remedies (freezer, bicarbonate of soda, mint tea) can temporarily reduce odour. They do not solve the problem of excessive sweating. If you want less sweaty feet rather than just less odour afterwards, you need to start with the skin itself.
Why PediSpray® takes centre stage here
Competitor blogs often end with “buy a better sandal” or “use powder or spray”. Our angle is more focused: in open sandals, the skin is exposed, so the main benefit lies in reducing sweat production. PediSpray® antiperspirant (Regular or Strong) is designed for this purpose, not to mask odours with perfume.
PediFris® Classic shoe powder remains effective in closed shoes or when wearing socks. In open sandals without socks, it is not honest advice to promise that powder will stay on the sole of the foot: it will not stay in place. Therefore, only use Classic if you are wearing socks, or stick to PediSpray® plus a clean, dry footbed.
This way, you can combine the good advice given by some shoe shops (material, changing shoes, drying) with what they cannot solve: overactive sweat glands on bare feet in the sun.
When should you see your GP or a chiropodist?
Do your feet remain soaking wet despite good care, or do you notice cracks, athlete’s foot, a fungal nail infection or open sores? Have them checked, especially if you have diabetes. Extreme excessive sweating (hyperhidrosis) sometimes requires medical advice in addition to self-care. Further background:what to do about sweaty feet en Thuisarts.nl on excessive sweating.
Ready to do it the other way round: skin first, then the footbed? Start with PediSpray® for sweaty feet. If you wear socks with sandals, add PediFris® Classic in the sock.
Frequently asked questions about sweaty feet in sandals
From “why do feet sweat in open sandals?” to choice of materials and odour from the footbed: the questions that keep cropping up in search results.
Why do my feet sweat in sandals?
Feet sweat in sandals because the sun, heat and friction keep the skin moist, even if the sandal is open and well-ventilated. A synthetic footbed often retains that moisture for longer than leather or cork, causing bacteria to produce odours more quickly.
Do open-toed sandals actually help with sweaty feet at all?
An open sandal is often more helpful than a closed shoe, but is no guarantee against sweaty feet if the footbed and skin remain damp. Combine a breathable pair with reduced sweating on the skin using PediSpray® and good dryness and hygiene.
Which sandals are best for sweaty feet?
Where possible, choose a breathable insole made of leather or cork that can absorb and release moisture, rather than smooth synthetic material that feels clammy more quickly. No style completely stops sweating: material and skincare go hand in hand.
How do you remove sweat odour from sandals?
Clean the footbed and straps, rinse them out and allow the sandals to dry completely, preferably by alternating with a second pair. Temporary odour-masking tricks can sometimes help, but the best way to prevent new odours is to ensure there is less moisture on the skin before putting them on again.
Does PediFris® Classic powder work in sandals?
PediFris® Classic only works in sandals if the powder stays in place, so it is not suitable for bare feet in open sandals where it falls out. When wearing socks, sprinkle Classic into the sock; without socks, use PediSpray® along with a clean, dry insole.
When should I see my GP?
Please contact us if you experience pain, open wounds, signs of infection, diabetes, or extreme excessive sweating that does not improve with self-care. Find out more about what to do about sweaty feet and visit Thuisarts.nl.
