Disclaimer: I don't have kids myself so this is a general question. Many of my friends do have children and I sometimes buy things for them. (Location Germany)
I wonder if "cheap" shoes you can buy on amazon or in cheaper stores (like H&M) are bad for the development of the feet of children.
I remember having cheap boots when I was around 10, and I started walking weird, so my parents started buying more expensive fitted shoes for me.
My best friends daughter (4years) started playing soccer, and we were worried about her ankle support, so I gifted expensive soccer shoes for her birthday. (which she already grew out of, ofcourse)
Do you have experience on how to keep the feet of your children safe during sports, and day-to-day wear? When buying shoes, how can I make sure that they are save to use?
