Walk into any shop with "smelly trainers" in your head and you'll walk out with the wrong can more often than not. Shoe spray is one of those terms that covers four completely different products, and only one of them touches odour at all.
We sell a shoe spray ourselves, the Shoefresh Perfume, and it does well for us. That's exactly why I want to be straight about what it can and can't do before you buy anything, ours or someone else's.
Why "shoe spray" causes so much confusion
Search for shoe spray and you'll get waterproofing sprays, leather cleaners, odour eaters and deodorant sprays all mixed into one results page. They sit next to each other on the shelf too, often in near-identical cans.
That's a problem, because they solve different jobs:
| Spray type | What it's for | Does it help with odour? |
|---|---|---|
| Waterproofing spray | Repels water and dirt on suede, leather and fabric | No |
| Cleaning spray | Lifts stains and marks off trainers | No, surface only |
| Shoe deodorant spray | Adds a fresh scent inside the shoe | Yes, temporarily |
| Antibacterial spray | Targets the bacteria behind the smell | Partly, surface level only |
If you're after something for wet weather, you want a waterproofing spray, not this article. If you're trying to stop your trainers smelling by Tuesday, keep reading.
Where the smell actually comes from
A quick bit of context before we get to sprays, because it explains why some of them barely help.
Sweat itself has almost no smell. It's mostly water and a few salts. The odour turns up once bacteria in your shoe start feeding on that moisture, on skin cells and on whatever's left in the lining. What they leave behind is what you're smelling.
Your foot can shed close to a hundred millilitres of moisture a day. That soaks into the insole and the foam. Leave the shoe in a hallway or a locker overnight and it's only half dry by morning, so the bacteria carry on exactly where they left off.
Any spray that doesn't change that cycle is buying you time, not solving anything.
Shoe deodorant spray, reviewed honestly
Our own product first. The Shoefresh Perfume is a shoe deodorant spray at €24.95, and I'll judge it the same way I'd judge anyone else's.
| Shoefresh Perfume | |
|---|---|
| Price | €24.95 (2-pack) |
| What it does | Leaves a fresh floral scent and tackles the bacteria sitting inside the shoe |
| How long it lasts | Roughly two days, depending on how hard the shoes get worn |
| What it doesn't do | It doesn't take the moisture out of the shoe |
| Best for | Gym bags, between matches, a quick fix before you head out |
| Not for | Shoes that smell because they never properly dry |
Don't expect miracles. It makes your shoes smell good, which is exactly the job it's built for. If the shoe stays damp, the odour comes straight back, however good the spray is.
The actual fix is drying the shoe out and dealing with the bacteria and fungi already living in it, which is what an active-oxygen shoe dryer and freshener is built to do. A spray works alongside that, not instead of it.
Use both and you're covering all your bases: the dryer deals with the cause, the spray gives you the scent on the day you actually want it.
Waterproof spray vs deodorant spray: don't mix these up
This is the mix-up we hear about most from customers who bought the wrong can.
| Waterproof spray | Deodorant spray | |
|---|---|---|
| Job | Repels water and dirt from the outside | Freshens the inside |
| Where you apply it | Outer material, before wearing | Inside the shoe, after wearing |
| Helps with smell | No | Yes, temporarily |
| Helps in the rain | Yes | No |
| Typical price | Around £8-15 | Around £4-10, or €24.95 for a 2-pack from us |
A waterproofing spray sits on leather, suede or fabric to stop water and dirt getting in. It does nothing for what's already growing inside the shoe. A deodorant spray does the opposite: it works inside the shoe and has no effect on how wet your feet get outside in the rain.
Some people spray waterproofing spray inside a shoe hoping it'll help with smell. It won't, and on some linings it can leave a film that traps moisture rather than releasing it.
Odour spray claims worth questioning
Pick up a can of odour spray for shoes and there's a decent chance it claims to kill 99.9% of bacteria. That figure usually comes from a lab test with a contact time and concentration a shoe never sees in real life. We don't put that kind of claim on our own packaging, because we'd rather say what a spray genuinely does: it tackles bacteria and fungi on the surface it reaches, not everywhere in the shoe.
An antibacterial spray, deodorant spray included, only lands where the liquid lands. That's the top layer of the insole. It doesn't get into the foam underneath, the seams or the toe box, which is exactly where a lot of the smell starts.
Supermarket own-brand sprays at £2-6 are honest about what they are once you know that: fragrance, sometimes a splash of alcohol, and a day of freshness. Fine for what it is, as long as you're not expecting it to sort out your football boots.
Can you use antiperspirant deodorant in your shoes?
We get asked this more than you'd think, usually by someone who's run out of shoe spray and has a can of the other kind in the bathroom cabinet.
Better not to. Antiperspirant is built for skin, not foam and fabric. The aluminium salts that block sweat glands have nothing to work on inside a shoe, because the shoe itself doesn't sweat. What's left is fragrance and a film that can go sticky and mark light-coloured materials. A product actually made for shoes will serve you better.
The same goes for kitchen-cupboard fixes doing the rounds online: bicarbonate of soda, rice, cat litter, the freezer trick. None of them are a real substitute for airflow and proper drying.
When a spray is genuinely enough
To be fair on both sides: there are plenty of cases where a spray is all you need.
- Your shoes smell occasionally, not every single time you wear them
- You need a quick fix before heading out and don't have time for anything else
- You've got shoes that sit in a cupboard and pick up a musty smell between wears
- You just want your trainers to smell nice, nothing more
And cases where a spray is going to let you down.
- You train several times a week and your shoes are still damp the next morning
- The smell is back within a day, no matter how often you spray
- You're dealing with athlete's foot or similar and treating your feet but not the shoe
- Your shoes are still wet the morning after they've been caught in the rain
If you're in that second list, you're spraying against the clock. No deodorant spray, however good, beats a shoe that never actually dries.
What a year of shoe spray actually costs
Worth doing the sum, because a spray habit adds up faster than people expect.
| Roughly per year | |
|---|---|
| A cheap spray every month at £4-6 | around £48-72 |
| A Shoefresh Perfume 2-pack every couple of months | around €150 |
| A one-off shoe dryer and freshener from around €129 | that price once, plus a few euros of electricity a year |
If a machine is out of reach right now, the ShoeDry Airo sits around €50 and uses ION instead of active oxygen. It's a genuine step up from spray alone, though it goes without the extra programmes, the heel dryer and the automatic start you get on the pricier machines.
The point isn't that spray is expensive on its own. It's that you keep buying it for as long as the actual cause sticks around.
FAQ
What's the difference between shoe spray and shoe deodorant spray?
Shoe spray is the umbrella term. It covers waterproofing sprays, cleaning sprays and deodorant sprays, and only the last one does anything for odour.
Does odour spray for shoes actually work?
It masks and partly tackles the surface bacteria, so yes for a day or two. It won't reach the moisture and bacteria deeper in the foam, so the smell returns once it wears off.
Can I use waterproof spray to stop my shoes smelling?
No. Waterproof spray works on the outside of the shoe and has nothing to do with what's causing the odour inside.
Is shoe deodorant spray safe on leather and suede?
Most products made specifically for shoes are fine. Alcohol-heavy sprays are riskier on untreated leather and suede, so test a small hidden spot first.
How often should I use a shoe deodorant spray?
After anything sweaty, or as soon as the smell starts creeping back. For everyday shoes that often means every other wear.
Is a shoe spray or a shoe dryer the better fix?
They do different jobs. Spray adds scent, a dryer removes the cause. If the smell keeps coming back, start with drying it out properly, and use spray on top for the scent.
Can I use a deodorant spray and a shoe dryer together?
Yes, and that's the combination that actually works. Dry the shoe first, then spray.
