Wow so many replies - thanks all for your thoughts. There's a bit of a split of opinion isn't there?
I think choosing to wear these ugly Hotters shoes when you are 30 or 40 is entirely different to picking them blindly at age 11. Even at Y8, once she knows the lay of the land at school I wouldn't be worried if she chose them. But kids can be ridiculously cruel and I really can't afford to buy another pair if it all goes tits up.
I've spoken with XP and DD this morning - as I suspected these were chosen in a state of shopping fatigue, and as most other options in DD's size were unavailable. They had been shopping for 5 hours - took 3 hours to buy trainers!!! I know I know. 
DD really wanted these Kickers - they were not available in her size in the shops -hardly suprising at this time of year.

She thought the Hotters were as close as she could get to the Kickers and they just wanted it all to end.
DD has had Kicker boots before and wasn't really keen on them so it's not that she needs to wear a certain brand.
School is quite strict re uniform - no trainers, no boots.
Neither I or DD are particularly brand focused (I make most of my own clothes
). I'm the queen of fugly comfy shoes & have ankle issues so never wear heels. I have three pairs of Ecco boots & they are gorgeous.
DD's new PE trainers are Nike and are the first pair of branded trainers she's ever had. She is really thrilled with them .
DD will be walking to school so comfort is a priority and I've vetoed the ballerina style shoes as impractical - not that she would ask for those anyway.
So the Hotters will be returned - she's not particularly devoted to them at all. She thought they were as close to the Kickers as we would find. The Kickers are available online and are quite a bit cheaper that the Hotters.
Can't believe I had a fairly sleepless night over this!! I started high school a month late and my Mum brought me the wrong shoes - I had worn them before we knew this and so they couldn't be returned. There was no question of buying a new pair. I had to wear them for THREE years getting bullied/made fun of by kids and picked on & hassled by teachers (like I could buy myself new shoes age 13!!) - it was horrible. So yeah, I really don't want DD to experience anything like that - its unnecessary.
Oh & I raised the matter with DD very gently - I didn't "shame her individuality" as some here thought I might be doing. I said we could exchange them and get some Kickers if she wanted to & she hugged me, thanked me and told me I was the best Mum ever.
