That would be extremely unusual. I can only think that the bar to success in 14cm was set quite low - simply being able to walk without falling - or that there was a platform involved somewhere. Or that she is or was a ballet dancer.
Hot Chicks at 13cm are famously difficult to master even by very experienced high heel wearers - so much so that Louboutin stopped making them. @higherheels is the only person with whom I’ve had any contact who feels confident walking in them, at least to go out for dinner. And I have a sense that she sets the bar pretty high, can walk easily in 12cm and even then she finds the need to work hard and practice with the 13cm Hot Chicks and her new and slightly higher boots.
i have a couple of friends who are serious high heel aficionados and their limit is 12cm, and one of them has quite a collection of Louboutins too. But nothing over 12cm. So I’m just finding it hard to picture someone slipping on a pair of 14cm court shoes and striding out of the shop unless there is some very unusual circumstance
