NiviaZion-1 Running Spikes Shoes, Yellow, 2 UK

Before I point out the details about this product, I'll have to counter this other review made by a plonker named "Gautam". He had mentioned that his son wore the shoe to school and the spikes came off. He's most likely retarded to buy a pair of shoes without knowing it's purpose.Now back to the point. This shoe is perfect for any kind of novice/beginners for running. The shoe is well made, perfect fit and not so bad when it comes to comfort. The shoes is yellow in colour and NOT blue and black as shown in the picture.It comes with 20 long spikes and 20 short spikes (Hard metal). A screwing tool is given to conveniently screw them in your shoes. Each shoe can carry 10 spikes. If you're running off road, feel free to use the spikes. If you're a track runner, I would recommend using the short spikes but if the long ones makes it better for you, go for it.These are perfect for practicing any kinda running exercise including marathon training, sprint running, long jump, etc.. But I'm not entirely sure if you can use it for an actual marathon itself. Maybe it dependsBut most importantly this shoes when equipped with the spikes, are NOT meant to be used on roads or hard rock terrain. They will get damaged and you can't blame the brand for it as it would be your own fault. So remove the spikes before making your way on hard surfaces and you're good to go.
