Found a great online Irish shoe company that has posture correcting insoles for children in their shoes and 15% off all purchases over €20. http://www.shoeboxkids.ie/
After a very disappointing experience of mis-fitting and trouble exchanging with a well known shoe company, we decided to look elsewhere and so we got shoes for our 3, 7, 9 & 11 year olds from Shoe Box Kids and they are all really excellent.
I am going to get myself a pair of the Muflon canvas style runners too because my9 year old is living in hers and reckons they are the most comfy shoes she has!
This is the link for them, they are like Converse but cheaper, with a thicker sole and IMO way more comfy!! http://www.shoeboxkids.ie/girls/model-43-651-red.html... (And 15% off, so a fab price as well!)
