I bought these shoes for my 11 year old son who's feet are growing at an enormous rate. He has owned 5 pairs of Kickers and is used to the way they fit, so I decided to buy size 9 shoe although he is a size 8. However they turned out to be too big, so I exchanged them for a size 8 in the Stratford Westfield store with no problems & the staff were fantastic.
The size 8 fit well.
