I am sure most of us who spend a considerable amount of time online would know that NSFW stands for Not Safe For Work.

When I came across this placard for school shoes a couple of evenings ago in Tesco, I couldn’t help but take a picture.

For the life of me, I could not understand why they used NSFW instead of some other initials. I didn’t even see this on the shoes, if it was the brand. So what’s so not safe for work are these primary school shoes?
With love
