Painful Standing with 16cm high heels without platform

In front of you, I am training to walk with the highest heels I never worn before and so long time!! 16cm high heels for someone with size 37 is just completely impossible to wear! but as I am wearing high heels everyday, I can do that a moment! it is painful but I can do it and you will see that I am walking and do normal stuff in my kitchen like I do in everyday life!!
