People who run, either professionally or just for fun and exercise, will benefit from wearing the right spiked shoes. Spiked shoes are useful because they give you the right traction for the ground you are 
running on. Regular running shoes without spikes will not give you the best grip for the surface. Spiked shoes however can give you the grip you need when you need it.
A slip while running can cause serious injury to muscles and tendons, spiked shoes keep your feet firmly planted where you set them. These shoes will keep you from a nasty slip or fall that could not only result in injury but also in time taken away from running to heal. A very bad fall could even cause you a permanent injury keeping you from the sport forever.
Another reason for wearing spiked shoes is the fact that they enhance your running speed. People who run in races need every advantage they can get during a race or training. Spiked shoes give them that extra grip they need to put more power into their stride.
The biggest advantage a runner may have over the competition is the right mental focus and mindset. You can not run effectively if you are worried about your feet. Wearing a pair of spiked shoes can keep your mind off your feet and firmly in the race where it belongs.
Not all spiked shoes are created equal however; there are different shapes and sizes of spiked shoes. Each sport has a spike shape and size that works best for it. For instance cross country runners will want spiked shoes with longer spikes. This is due to the differences in terrain they will need to cross. Long spikes can sink into a muddy slippery trail and anchor your feet to firm ground and allow you to keep on your feet and impetus to power through mud. Wearing spiked shoes with long spikes on a track however could cause serious problems. The longer spikes on these spiked shoes will not be able to grip the track properly and will throw you off your stride if not force you to slip and fall.
The right kinds of spiked shoes are an advantage to runners. They keep them from falling or slipping and getting injured. They also add to your running ability. Due to the added traction you will enjoy more power and speed when you run. The wrong kind of spiked shoes for your particular sport however can be detrimental and cause accidents.
