Great shoes for 14 year old medium sized girl (size 8.5). Breathable and comfortable not just for running, but also day to day walking. Unlike other athletic shoes with breathable material on the front and side, this one seems a lot sturdier. Puma is a German brand popular in Europe. I would still recommend buying separate insoles for about $20 - the ones provided with the shoe may not last that long - which is the case for sports shoes in general.
