European Brands School Shoes - size/width info

[Olympias]

I've been googling for ages and still can't find the info anywhere.

I am trying to find the answers to two simple questions:

1. For a given brand, are the shoes run true to size or on a big/small side.
2. From narrow to super wide - where are a given brand shoes are?

I am interested most of all in Primigi, but will be grateful for any other euro brands, such as Geox, Ricosta, Naturino, info.

Thanks you!

We have had Primigi and Ricosta shoes before and I think both of those come up quite narrow.
