1. Start with the training surface
Ask your club where most sessions take place and which soleplates are allowed. Indoor training requires a separate indoor shoe. Outdoor boots are not a substitute.
2. Measure both feet
Measure feet in the late afternoon or evening if possible. Have your child stand on a sheet of paper with their heel against a straight edge. Mark the longest toe and measure the distance. Repeat for the other foot.
Note both foot lengths in centimetres. Compare the longer foot with the brand’s size chart. Check whether the chart lists foot length or the shoe’s internal length . These are different measurements; do not add a fixed allowance to a chart based on foot length.
The adidas kids’ size chart is an example of brand-specific measurements. For another brand, use its own chart. An EU size is only a starting point for trying boots on.
3. Try them in motion with football socks
Have your child try on both boots with the socks they wear for training. Toes need room; the heel should not slip out when walking or stopping. Ask your child to walk a few steps, step sideways and stop gently.
Ask specific questions: “Does it press at the sides?”, “Do your toes hit the front?” and “Does your heel slip?” A quick “it’s fine” often tells you little. Buying oversized boots to allow for growth does not help if the foot slides inside.

4. Fastenings must work in everyday use
Laces allow targeted adjustment. Hook-and-loop straps or other easy-to-use systems can be practical if your child cannot yet tie laces confidently. Have your child put on and fasten the boots themselves.
Laceless models must fit well without adjustment. A high, sock-like collar should not make getting the boots on unnecessarily difficult. What matters is whether the specific model fits.
5. Check the fit again during the season
Check fit regularly, especially after growth spurts or if your child suddenly dislikes wearing the boots. Repeat the measurements and movement test. New boots may be needed even if the old pair still looks good on the outside.
With second-hand boots, also inspect the soleplate, studs, stitching and lining. Worn studs, separating soles or badly misshapen heel lining are reasons to choose another pair.
6. Budget for use and growth
Fit and a suitable soleplate matter more than a famous product line. Compare the exact version, not just its name: kids’ and adult models, as well as different quality tiers, can vary.
A previous-season model can be a useful option if the size, condition and surface approval are right. When shopping online, check the return policy and first try the boots on indoors, keeping them clean.
