In recent times, it's been noted that an increasing number of people on the photo-sharing website - including celebrities such as Bella Hadid and Kourtney Kardashian - have started to lift one of their heels off the ground while posing for a snap, Mirror Online reports.

The theory is that by changing the angle of the foot, the individual succeeds in making their legs look more well defined and, in turn, more attractive.

Unsurprisingly, the trend has been copied by a huge number of non-celebrities who are keen to emulate their heroes.
