Soaking football boots in water, or spraying them, is not something you need to do, and as far as we could find, no manufacturer names it as a method. Retailers actually warn against hot water and full immersion. You get new boots to fit better by breaking them in gently.
Sources on this are limited. Below is what we did find, and where we honestly do not know.
Should you try soaking football boots in water?
No, you do not need to. We found no official manufacturer source on soaking or spraying with water, and no warranty terms on it either. Brands do not recommend heat or full immersion.
Check the terms and the care advice from your brand before you try anything yourself. The warranty is the first thing at risk, and it is the part you cannot repair afterwards.
Soaking or spraying football boots: what do the sources say?
Retailer guidance says that submerging a boot fully can damage the materials, pull out the support from the boot and let mould develop inside. Hot or boiling water can attack the glue that holds the sole and upper together.
Leather becomes more supple when it is damp, but direct heat is bad for leather. With synthetic material, wetting may work, but do not overheat it. Several guides recommend against hot water altogether.
Why do people try it at all? Mostly with a tight leather boot, and a wet-and-wear trick is passed around on pitches and in changing rooms. The idea is that damp leather moulds to the foot as it dries. The risk is that the same moisture, followed by heat, ruins the boot you have just bought.
How long should football boots go in warm water?
There is no manufacturer advice on that. The mildest version we found comes from a US retailer: wet the upper and soleplate with warm water, and then wear the boots in socks for at most an hour. That is a shop tip and not a test of ours.
Given the risks that retailers mention, it is better to choose breaking in first.
What should you do with new football boots?
- Try them on with your football socks and check that they fit well. How that should feel is covered in how football boots should fit.
- If you have leather, break it in. You can read how in how to break in football boots.
- Knit and synthetic give little. If the boot is too tight, it is probably not the right one.
There is more on stretching, and what does and does not work, in how to stretch football boots.
When is a wet boot normal?
Boots get wet anyway: a sodden winter pitch or a wet 3G pitch will soak them without any help from you. That is not the same as soaking them on purpose. After a wet match, let the boots dry at room temperature, away from radiators, and do not leave them in a closed bag. Washing and drying football boots covers how to do it without harming the fit.
What about wetting just one pressure spot?
Some players only dampen the spot that pinches, for instance over the little toe, and then wear the boot at home until it dries. This is milder than soaking the whole boot, and it only makes sense with real leather, because synthetic leather and knit barely respond. It still carries the same risks of marking the leather and weakening the glue near the soleplate, so keep it small, let the boot dry slowly at room temperature and stop if the material looks stained or stiff.
If the spot still pinches afterwards, the problem is probably the shape of the boot and not the leather, and water will not change that.
What is the best way to make boots fit your foot?
Choose a model that suits your foot, and then you do not have to force anything. Use the football boot adviser if you do not know where to start. If the boot pinches after a few sessions, see what to do when football boots pinch.
