First of all, I am using the original version of FIFA 18 (Latest update). Hence, it will work for the owners of original game with latest update. For others, it should work but no promises as I have no means of testing.
1) ADIDAS's Cold blooded pack [Predator, X, Nemeziz] added.

2) NIKE's Fast AF pack [Hypervenom, Magista, Tiempo] added.

3) NIKE's Flyknit Ultra [All 4 color variants at same time] added.

4) NIKE Vapor XII Elite and NIKE Superfly VI Elite added.

5) PUMA [One 18, Futures] added.

6) Specialized versions [ CR7, MESSI, NEYMAR, HAZARD, GRIEZMANN, JAMES RODRIGUEZ] added.

7) I did some experiment replaced all EA's default color variants with NIKE Vapor XII Elite, so thats like 23 extra vapors.

8) All boots unlocked (Courtesy of RedMessi's YT tutorials, show him some love)

9) All boots name updated (Courtesy of Houss3m, show him some love)

10) Many of the boots from previous versions are still in there, like Nike's Fire & Ice pack.

11) All the boots will be assigned to the players to any squad of yours except for few Pumas but thats nothing and can be easily tweaked.

Quick shoutouts to:
1. MeBoots for  "Nike Tiempo Legend VII ''Fire & Ice'' Pack", he made for FIFA 14.
2. Nabo78 for "Nike (Magista, Vapor & Superfly) Fire & Ice Pack", he made for FIFA 16.
I used their textures and made them compatible for FIFA 18 as those boots still made to this bootpack, show them some love too.

Thanks for patience and love.
Till next time.
