This is how Kate Middleton walks in high heels all day

BRB, ordering a pair immediately

Meghan Markle's shoes are often too big so they won't scuff her feet, and she's certainly not the only royal to have a shoe hack, given that they spend an inordinate amount of time on their feet during official assignments.

The Queen has someone who breaks in new shoes for her, however the Duchess of Cambridge has an altogether quicker (and cheaper) trick to glide around in high heels all day.

According to a 2015 by Vanity Fair, Kate simply adds leather sole inserts to her shoes. She apparently uses £14.95 insoles by British brand Alice Bow, which come in a variety of colours (and they are currently 20% off) and are made from Italian leather. The comfy shoe inserts reportedly turn all-day high heel wearing into an easy feat, and the Duchess is certainly well placed to put them to the test.

'Kate has ordered a couple of packets, she thinks they are great,' the insider told VF of the soles. 'There has been talk of the Duchess wearing the insoles, but we cannot comment either way. We have seen a massive surge in site visits however.'

This is no surprise, as according to the official royal website, businesses shouldn't exploit the royals for commercial purposes, especially if they're gifts for special occasions, though again royals aren't meant to accept most gifts.
