RESPECTFUL FOOTWEAR: what is it?

A shoe is only respectful if it has the ideal amount of space at the toe, with room for the toes to move and grow healthily. This space should be between 0.8 and 1.2 cm.
How can I confirm that the size is ideal? By testing the insole, if it is removable:
- Between 0.8 and 1.2 cm: ideal for the child to be comfortable, with room to grow and make the most of the shoe;
- More than 1.2cm: large;
- Less than 0.5mm: it's time to change the size, because it's too small.
Most barefoot brands already take care to include this allowance in the size guide and it is not necessary to add it, however, it is an aspect that should always be confirmed depending on the chosen brand.
When the brand indicates a range of values, it usually includes the clearance. When it indicates the length of the insole, it is necessary to add between 0.8 and 1.2 cm.
