I have worn 4 inch heels with saris and touchwood have never fallen or tripped. I think that happens when ur petticoat and sari aren't the same level. You shud put ur heels on before you wear ur petticoat and then drape the sari. It shud hang 1cm above the floor with ur heels. Most ppl don't have practise walking in saris. When i first became a fan i bought a cheap one and wore it round the house, did my housework etc in it. This way you become used to sitting, walking and even crouching down in them.(u have to if u have kids) so try it girls.
