Shoppers at supermarket giant Asda have been left in awe after spotting a 'magic' hidden detail inside some £20 school shoes.
The girls' shoes, which come in a size 8 jnr - 4, look like a normal pretty black pair at first.
But hidden inside the heel is a special treat - a minature Elsa doll from the popular Disney film Frozen.
Thanks to their hidden detail the shoes have now gone viral, after one impressed parent shared them on Facebook.
"Does anyone remember the Lelly kelly shoes with the doll at the bottom from years and years ago," the original poster wrote.
"Just found these in Asda my twins are obsessed £20."
They added: "Edit- might have been Clark’s not Lelly Kelly."
The post has proven wildly popular, and thousands of people have since liked, reacted and commented on it, reports the Mirror.
One Facebook user wrote: "Clark’s magic keys. Key in the bottom of shoe and you got a key badge too!
"I’m 35 in a fortnight so that’s going back some years haha! Best shoes ever!"
Another said: "They were called magic steps from Clark’s and they had a key, if you lost the key you were screwed unless you had a friend who also had a pair. I always used to have them."
"Yes can remember those shoes from Clarks also can remember a key to get in the bottom of them for a secret surprise... Wow trip down memory lane or what!!!" exclaimed somebody else.
Others pointed out how much teachers dislikes them: "Lovely shoes, every kids dream and every teachers nightmare. Haha."
