lol! I don't know about Nike. I don't see why they would. But to answer your question, horse shoes in my friend's boarding barn are changed every 6-8 weeks. Another way to tell is that a horse's hoof will start to outgrow the horseshoe. Not in the sense that you need the size up. Horses' hooves are like finger nails, they grow and you trim them back. So you would have to have a farrier come in and change the horse's shoes and trim its feet. I hope this explains things for you.

it does...I feel like a complete retard now not having known that but that's what E.L. is for I guess...thx, Alycia! Scott

Also, horseshoes do wear down (aluminum quicker than steel) but they can be reused 2 or 3 times depending how much you ride. :o)

Another thing, somethimes you have get new shoes or have the farrier put them back on if the shoes start to get loose. You can tell the shoe is starting to get loose when you can shift the shoe back and forth, the nails on the outside of the hoof start to pop out, and if when you ride you hear the shoe lightly slap up on the bottom of the hoof again when the horse is walking/running. If your horse's shoe starts to get loose it's best to fix it right away. The same for if it looses a shoe. This could injure the horse and/or cause lameness.

and depending on the work your horse may not need shoes. but my horse's feet grew alot and she needed trimming ever 4-6 weeks

when he tells you that it needs changed ur horse will speek to u
