Brief Summary

In the era of science and technology, footwear has become not only an essential item of clothing, but also another tool for the optimal development of children, the improvement of work and sports performance or the prevention and treatment of pathologies. The anthropometric characteristics of the child's foot differ considerably from those of the adult foot, in fact, it is not until the age of 18-19 years that the structure of the foot is finally consolidated. Therefore, it is essential that footwear manufacturers know these characteristics to achieve an adequate design. Current scientific evidence highlights the importance of considering the unique morphology of the infant foot, as well as the high functional demands to which footwear is subjected at these ages. There is a lack of studies that analyze in detail the shape of the child's foot.

Outcome Measures

Primary Outcomes (2)

• Shoe test

  Using different reference points of the foot, the areas to be measured will be measured in millimeters. They are collected by digitizing the foot and ankle of each person, using the 3D scanner and the IcadPie Software.

  Up to 3 month

• Plantar pressure

  Based on sensory technology, the sensors are placed along a fixed platform, connected via a universal serial bus cable to a computer and appropriate software. The sensors, by supporting pressure, generate a potential difference that can be measured. This electrical voltage value is detected by the sensors themselves, and a computer program reinterprets it in the form of a graph with the captured values. The graph consists of a plantar footprint with a range of colors, according to the relative baropressure captured. This instrument would provide us with quantifiable data about how load patterns behave in bare feet and shoes, in order to establish useful comparisons in our study

  Up to 3 month

Study Arms (1)

Anthropometric study of children's feet and healthy standard last design:

EXPERIMENTAL

An anthropometric study of the feet of the subjects included in the sample will be carried out. The variables of interest used in this work are collected by digitizing the foot and ankle of each person, as well as through an anonymous questionnaire, which the study volunteers and their parents or legal guardians fill out and deliver. From the data collected, 5 models of healthy standard last will be produced that are adapted to the anthropometric characteristics of our study population: sports last, boot last, sandal last, ballerina last and moccasin last.

Diagnostic Test: Anthropometric study

Interventions

Anthropometric study DIAGNOSTIC_TEST

Once the 5 models of lasts have been produced in phase 1, certain shoe models will be designed and manufactured based on these lasts at random and at the free choice of the designers of a footwear company. These models will then be physically tested on children to analyze their effects on walking and walking.

Also known as: Design and manufacture of shoes and fit tests

Eligibility Criteria

• Age: 12 Months - 15 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Child (0-17)

You may qualify if:

• School-age boys and girls with foot sizes between 20 and 41
• Attending school and belonging to public, private or concerted schools, to guarantee the variability of the sample in terms of type of school.

You may not qualify if:

• Present a severe structural or functional alteration of the foot, which prevents an adequate digitization of the foot and ankle with the hardware and software used to collect the samples.
• Not having the signature of the informed consent or express authorization of the parents or legal guardians to carry out the measurement and the subsequent processing of the data.
• Inability to stand or walk independently.
• Present crying or fear, not being cooperative or engaging in inappropriate behavior.
