does it have difference to 200m time, for example if spikes are like these :

running spike for events of 400 metres and up.
or better buy sprint spikes up to 400 ?
Shouldn’t make a difference at all.
Compared to sprint spikes middle distance spikes usually have more flexible spike plates and slightly cushioned heels. If the shoes fits and your big toe can bend freely it will be fine.
Yes it makes a difference when you get rid of the 1cm heel. I would not get spikes with a heel pad unless you’re planning to triple jump or high jump as well as run the 200.
so these shoes ar not very good for 200m http://store.nike.com/index.jsp?country=GB&lang_locale=en_GB&l=shop,pdp,ctr-inline/cid-300/pid-210787/pgid-216000 ?
They are ok but I think a spike with no heel may be better.
Where you get in trouble with the heel is around the curves: The heel of the spike touches the track more and you’ll end up racing like a distance runner (more GCT). You can even run 60 or 100 even in long distance spikes without much effect, because you are (or you should be) sprinting on your forefoot. The problem with mid/distance spikes is greater for the 400 than the 200 because in the 200 you’re accelerating and not going as fast for much of the curve.
You can do training in distance spikes, but if performance really matters, I’d stick to racing 200 and 400 in real sprint spikes.
