A school in north London has gone shoe-free in a bid to make children 'feel more at home' in classes.
Pupils at the Torriano School in Kentish Town are being told to take off their shoes when they come inside in a move bosses hope will 'take away the hierarchy' between children and teachers.
The move comes after teachers from the school visited Finland, Iceland and Sweden, where the practice is more widespread.
Headteacher Helen Bruckdorfer told?The Camden New Journal: 'What resonated is this connection between home and school, which is very different to the way we organise school, and the need for children to feel comfortable and relaxed within the school setting when they come into the building.
'When you get home you come in and take your shoes off because you just sort of release that energy. You are able to think more clearly.'
The policy is being trialed in the school's nursery, reception and Year 4 classes, but could be rolled out to the whole school if successful.
Ms Bruckdorfer added: 'It takes away the hierarchy because all of us, teachers and children, have to take our shoes off.'
She said the move is very popular among children, who have become 'calmer' since they shed their shoes.
The school's new policy follows research by Bournemouth University, which claimed 'shoeless' children get better grades, behave better and are more likely to arrive to school on time.
But critics have raised questions over how effective the policy really is.
Chris McGovern, from the Campaign for Real Education, said the much-vaunted Finnish education system should not be seen to have all the answers.
He told MailOnline: 'Not all children wish to learn within a smelly feet environment. Let parents and pupils decide.
'Almost 40 percent of primary school pupils are not reaching the govt's floor standard in literacy and numeracy. Learning in one's socks is unlikely to solve this problem may encourage to shoe-kicking bullies.'
Holding Hands 握手
A bill passed in Tennessee declared hand-holding a 'gateway sexual activity,' with teachers facing firing for even demonstrating the action.
Surprisingly, the ban on hugging isn't a one-off rule at a select school, but a trend that seems to be spreading. Schools in Portland and Florida started instituting these rules in 2010, while administrations in New Jersey, Brooklyn took it upon themselves in 2012. For all, the reasoning appears to be the same: Respecting personal space and "unsuitable interactions" between students.
Red Ink 红墨水
At schools in both Australia and the UK, green ink has replaced red ink in marking children's paper because of its 'confrontational' nature.
There's plenty of debate about the best possible bookbag for kids -- but one school in Michigan doesn't allow bags into the classroom at all. Citing safety concerns in lunchrooms and classes, the high school asked students to keep returning to their lockers between classes to retrieve the appropriate books.
Yoga Pants 瑜伽裤
An Ottawa school banned yoga pants -- unless the tight bottoms were covered up with long shirts.
Best Friends 好朋友
No more BFFs for you, British kids! At a few UK schools, teachers are preventing children from making "best friends" in an attempt to save others' feelings.
Ugg Boots UGG牌靴子
It might get chilly in Pennsylvania, but students there won't be allowed to wear their sheepskin Ugg boots into class, thanks to the potential for storing contraband like cell phones in the roomy footwear.
Baggy Pants 阔腿裤
You may have thought baggy pants were more of a '90s thing, but schools today are continuing to push for bans on the sagging pants, with some schools claiming it interferes with learning, and others saying the style is related to gangs.
Skinny Jeans 紧身牛仔裤
And then there's the opposite end of the spectrum. Much like yoga pants, skinny jeans have been banned in schools all over the place, due to their lack of modesty and distraction factor for the opposite sex.
