where to get spike/track shoes

Hello Qatar Living. The question says it all. Where can i find myself some good preferably Nike track shoes for long distance runners. I've recently joined the national team and am getting screwed over every time we have a track session because I dont have spikes. currently, i am desperate for a pair and tired of begging people for some. One last time, where can i get these shoes. i dont really care where i can get them as long as i dont have to order them.

Thanks
