I'M 6'1 AND I WIEGH 190 AND RUN A 5.0 IN THE 40 TIME AND IM GETTING READY TO PLAY DEFENSIVE END ON MY VARSITY FOOTBALL TEAM AND I WANNA KNOW THE BEST CLEATS TO GET BUT I ALSO WANT THEM TO GIVE ME BETTER SPEED AND EXPLOSION

get some under armors that are detachable they are the best cleats on the market today and they have some really flashy colors(scare some ppl).

Under Armour has pathetic shoes.

Nike has by far the best shoes and here is a site with their best ones that you should take a look at.

Any of the shoes on this site would be great bur because of your position I would get high tops and not low tops because D-ends need more ankle support becuz you get stepped on alot.
