For sport, prioritize movement and support. For school or daily play, look for durability, comfort and room that does not get in the way.
| Garment | Decathlon | Nike | SIZES tip |
|---|---|---|---|
| Sneakers | Practical by sport | Sports and lifestyle models | Measure feet in centimeters |
| Technical tops | Built for movement | Discipline-dependent fit | Check chest and length |
| Tracksuits | Comfort and daily use | Collection-led fit | Check waist and sleeve |
| Sports coats | Designed for activity | Line-dependent | Allow room for layers |
Why use changes sizing
A training top does not need to fit like a school hoodie. For sport, too much room can get in the way; for daily use, a little room can be practical.
What to check before buying
For shoes, use centimeters and width. For technical clothing, check stretch and arm movement. For tracksuits, check waist and length after washing.
SIZES tip: use this guide as a practical reference and always confirm the official brand size chart when the garment includes its own measurements.
How to use SIZES
Save foot length, height, chest and waist, then add notes by activity. Football, school and walking do not need the same fit.
Final recommendation
Choose size by activity. Technical sport needs stable fit; daily wear needs comfort and moderate room.
FAQ
Do Decathlon and Nike fit the same for kids?
Not necessarily. The sport type also changes the expected fit.
What should I check in sports shoes?
Centimeter length, width, heel support and toe room.
Should I buy larger so it lasts?
Only if the child can move well. In sport, too much room can be uncomfortable.
