The horseshoe is considered a lucky charm in the West as well as in India ! The shape of the horseshoe describes the ideal land configuration of Feng Shui, hence it is considered a favourable shape as per Feng Shui too.

In India, people have traditionally considered the horseshoe as a lucky charm and used it by affixing it above their main door on the outer side, for protection and good luck. It is said that the real horseshoe which a horse has worn and which has been energized by the horses galloping, is very lucky ! If you happen to find such a horseshoe you can affix it above your main door on the outside above the door frame. Since the horse­shoe is of metal element avoid its usage for East and South-East facing doors. It is more useful for West, North-West and North facing doors.

The ideal way is to affix the horseshoe with its prongs pointing downwards. A lot of people affix the horseshoe with the prongs pointing upwards. This is also not wrong. When the horseshoe is affixed in this way it is said to bring in good luck, but when it is affixed with the prongs downwards, it is said to even protect the house from evil spirits and negative energies!
