Children's feet and footwear

"The foot is the foundation, and if that isn't working correctly, nothing will"

We all know children grow, most of the time, too quickly. Especially their feet.
So how do we target this, and what is the impact if we don't? This blog post is to discuss the impact of rock climbing footwear on children's feet, especially due to the growing market of climbing shoes available for the younger climber.

The first thing to note is the rate of growth in children's feet.

In girls, the foot grows linearly fashion in both width and length from 3 to around 12 years old, and stop growing completely around 14 years old.
In boys, the foot grows in a linear fashion in both width and length from 3 to around 15 years old, and stop growing around 16 years old. 

A child's foot can grow 3 sizes in a year, so it is really important to monitor growth closely.
Children's feet also sweat more, so need more ventilation from their chosen footwear to prevent poor foot hygiene.

A study done into the German Junior National Team found a higher incident of hallux valgus in those members who had spent a relatively longer time active in indoor competition climbing, as well as 74% of the team having feet pressure marks compared to 28% recreational climbers, indicating tight fitting shoes (even though the importance of tight fitting shoes in indoor walls is less important due holds being relatively larger than outdoors, enabling children to wear shoes too long if required).

Another problem with the climbing shoes is the supinated foot position as mentioned in the previous foot and ankle post, which can put a child more at risk of ankle injuries. With children, this puts them more at risk of ankle growth plate, as their growth plates are not fully formed until the age of 17 years old.

Rigid shoes or too much cushioning can limit the development of the connective tissue, muscles and bones, due to these structures requiring the mechanical stimuli to aid the growth. This is especially important as the connective tissue strength and foot flexibility does not stop forming until the age of 15.

Finally, shoes that do not cut into Achilles tendon are recommended, as this can cause shortening of the tendon when the calf is flexed, causing torsion in the plantar fascia leading to a higher arch causing a change in the biomechanics of the foot.

Any children's shoes that are too tight or too small will limit the growth of a child's foot at the key stages of their development. A poorly developed foot will impact a child for the rest of their life.

In summary, a child's climbing shoe needs to be:

  • flexible
  • not cutting into the Achilles tendon
  • not too much cushioning
  • not restrictive
  • needs ventilation
  • review the sizing often

Coming next, will be the impact of climbing on children's fingers.
