Read about choosing bootsNew boots and a long session are how most blisters start.
This page gives you a five-session break-in, a fit and sock check, and a quick decision for when a hot spot appears at the side of the pitch.
Child blisters from football boots come from rubbing, so stop the rub: boots that fit, sports socks and short wearing periods for new ones (NHS) (Knapik review). Break new boots in over a few short sessions before a long one, and end each break-in stage at the first hot spot, a red patch that stings. In a normal session, stop at a hot spot and cover it before play restarts (NHS) (BMC). Do not burst a blister yourself. Let a burst one drain before covering it with a soft plaster or padded dressing (NHS). Ring 111 or see a GP if it is very painful, keeps coming back or looks infected (NHS). No source tests this on children's football, so the break-in plan is this page's own.
I once sent a child to a Saturday session in boots that had only ever been worn in the shop, and carried them home from the car park.

Short wears first
The NHS says to break in new shoes gradually, with short wearing periods (NHS). That line is the only part a source backs. The five stages below are my own plan built on it, and the minutes are a suggestion, not a rule.
| Stage | What to do | Stop if |
|---|---|---|
| 1 At home | Wear them round the house for 15 to 20 minutes, in the socks they will play in. | Anything rubs or stings. |
| 2 Walk and jog | A short walk, then a gentle kick-about on grass. | A hot spot appears. |
| 3 Short game | Ten minutes of normal play. | A hot spot or sore patch appears. |
| 4 Half a session | Play for about half of a usual session. | A hot spot or sore patch appears. |
| 5 Full session | Wear them for the whole session. | A hot spot appears. Go back a stage next time. |
Move to the next stage only when the last one passed without a sore spot. If a stage rubs, drop back one and try again another day.
No source says how many sessions a break-in needs. Treat five as a starting point and check both heels and toes after each one.

Fit and socks first
A boot that fits and a sock that stays smooth do most of the work. Run this check before the first wear and again whenever the boots start to rub.
Fit. The NHS asks for comfortable, well-fitting shoes (NHS), and the soldier review lists properly sized boots as a way to cut friction (Knapik review). A common tip, not a source: try boots on late in the day, with the child standing and wearing the socks they play in. For sizing, read the fit check and sizing.
Socks. The NHS suggests thick socks for exercise, such as moisture-wicking sports socks, and changing socks if feet sweat (NHS). The review points the same way, with socks that reduce friction and moisture (Knapik review). No brands here, only the type.
Laces. Snug through the middle, so the heel does not lift and the foot does not slide forward. Lace locking, a way of looping the top laces to hold the heel, is a common tip with no independent source, so treat it as an idea to try. For ways round the knots, see lacing so the foot stays put.
Dry boots. A damp boot is likely to rub more, so let boots dry fully between sessions. That is my own reasoning, and no source here tests it.
The review is about soldiers on marches, and the hillwalking article is for adults. Neither tests children's football boots.
At the side of the pitch
I used to say "run it off" about a stinging heel, and I wasn't the one walking home in it. Decide at the pitch, before a hot spot turns into a blister. The table gives one action for each thing you might see.
| What you see | What to do |
|---|---|
| A red, warm patch that stings (a hot spot) | Stop. Take the boot off, check the sock is smooth and cover the spot with a soft plaster or padded dressing before play restarts (NHS) (BMC). The hot-spot idea comes from a hillwalking article, so it is borrowed from adults. |
| An unbroken blister | Do not burst it. Cover it with a soft plaster or padded dressing (NHS). The NHS says not to wear the shoes or use the equipment that caused a blister until it heals, so stop for the day and keep the boots off (NHS). A pharmacist can advise on hydrocolloid dressings (NHS). |
| A burst blister | Wash your hands, let the fluid drain and do not peel the skin, then cover it (NHS). Keep it clean. |
| When to get help | Ring 111 or see a GP if it is very painful or keeps coming back, or if the skin is hot with green or yellow pus (NHS). A GP can burst a large or painful blister with a sterilised needle (NHS). |
Whether to carry on is your call. At a hot spot, stopping means pausing to take the boot off and cover the spot; once it is covered and comfortable, the game can carry on. During a break-in stage, a hot spot ends that stage. An actual blister means stop for the day. That is my own judgement, not a line from any source.

Look, then decide
Wash and dry the foot, then check both heels and toes. If there is a blister, keep it clean and dry, and do not wear the boots that caused it until it heals (NHS).
If blisters keep coming back with a correctly fitted pair and good socks, the boot is wrong or the size has changed. Go back to choosing the next pair.
If it hurts but the skin is unbroken, that may be a different problem: read about a sore heel with no skin damage.
What is known and what is not
Do not burst a blister yourself, cover it with a soft plaster or padded dressing and break in new shoes with short wearing periods. Wear thick socks during exercise, such as moisture-wicking sports socks, and do not wear the shoes that caused a blister until it heals. Ring 111 or see a GP for a blister that is very painful, keeps coming back or looks infected. That is the NHS page on blisters.
Blisters come from boots rubbing the foot, and properly sized boots and friction-reducing socks help. That is a review of foot-blister prevention for soldiers. It covers soldiers on foot marches.
Act on hot spots early and a blister may never form. That is the British Mountaineering Council's advice on friction blisters, written by a doctor for hillwalkers.
The NHS page is general advice. The other two sources are about soldiers on long marches and adult hillwalkers, so they do not prove what will happen in one child's football boots. The break-in plan is this page's own.
Quick answers
Well-fitting boots, sports socks and short wearing periods for new ones (NHS).
No source says. This page suggests five short stages, moving on only when the last one is comfortable.
No. The NHS says do not burst a blister yourself (NHS).
The NHS suggests thick socks during exercise, such as moisture-wicking sports socks, and changing them if feet sweat (NHS).
If it is very painful, keeps coming back or shows hot skin and green or yellow pus (NHS).
That is your judgement. Once a hot spot is covered and comfortable, the game can carry on, but an actual blister means stop.
