Pajar - Fero 2.0 - Winter boots tested

I understand that an EU size 43 is the equivalent to a UK size 9. I need full clarification that the UK size 9 of these shoes the the size on the label inside the shoe as well as the size on the box. I tried to buy a pair of these shoes from snow and rock the box of the shoes the staff bought out from the stock room said ‘Size 9’ I am fully confident I am a UK size 9 but when I tried the shoes on I realised that the interior label attached to the shoes was displaying a UK size 8.5 so the size labels were incorrect and the size Uk 8.5 did not fit me and they did not have a size UK 9. I would like to order a pair of these in EU size 43 equivalent to UK size 9 but I need to be certain that the label inside the shoe, NOT the box label is genuinely showing a UK size 9 before ordering. Could someone please check the interior label in the shoe to ensure that the precise shoe size is UK 9. Because when I tried to order from snow and rock the UK size on the box was incorrect and inaccurate to the label size inside the shoe. Thank you.
Yours faithfully,
Geoffrey Bocking
