Slitesterk EKO Shoe Stretch Spray – say goodbye to pinching shoes
New shoes that are just a little too tight are one of life’s small frustrations. The good news is that leather is wonderfully forgiving, and this Slitesterk EKO stretch spray is the gentlest way to coax it into shape. Spray it on, wear the shoes in, and those pressure points across your toes or along the sides gradually ease away. It works on genuine leather of all kinds — smooth leather, suede and nubuck — so it is a brilliant all-rounder to keep in the cupboard.
What I love most about this one is that it is part of the Slitesterk EKO range. The formula contains no harmful ingredients, and the bottle is made from 100% recycled plastic and is itself fully recyclable. Comfortable shoes and a lighter footprint — that is a combination I am happy to recommend.
Why does it work? The formula relaxes the natural fibres in genuine leather, so instead of forcing your foot into a stiff shoe, you gently persuade the leather to give a little exactly where you need it. Because it treats the material rather than your foot, the extra room stays put once the leather dries into its new, roomier shape.
Why choose Slitesterk EKO Stretch Spray?
- Relaxes tight spots. The formula softens the leather fibres so your shoes stretch to the shape of your foot and stop pinching.
- Works on all genuine leather. Suitable for smooth leather, suede and nubuck alike. (It will not work on synthetic materials, which do not stretch.)
- An eco choice. No harmful ingredients, packaged in 100% recycled and recyclable plastic.
- Simple and effective. No special tools needed — a thick pair of socks and a short walk do most of the work.
- Great with a stretcher. Pair it with a shoe stretcher for stubborn areas and you will get an even better result.
How to use Slitesterk EKO Stretch Spray
- Shake the bottle well before use.
- Spray the tight areas generously — you can treat both the inside and the outside of the shoe.
- Pull on a thick pair of socks (or even two), slip on the shoes and walk around while the leather is still damp.
- Let the shoes dry fully, then repeat the treatment if you need a little more room.
Haico’s tip
If you are treating the outside of a coloured shoe, test the spray on a hidden spot first to check the colour holds. When in doubt, just spray the inside — it still softens the leather where it counts. And for really stubborn pinch points, use the spray together with a shoe stretcher overnight; the two make a brilliant team.

Frequently asked questions
Does it work on synthetic shoes?
No, only on genuine leather, suede and nubuck. Synthetic materials do not stretch, so the spray cannot help there.
How many treatments will I need?
Often one is enough for a slight pinch, but you can safely repeat it a few times for a snugger fit. Let the shoes dry between treatments.
Can I spray the outside of my shoes?
Yes, though I would test a hidden area first on coloured leather. If you would rather play it safe, spraying the inside works well too.
