I think the best boots are World Cups and Copa Mundial which have been going for over 20 years and still rival the top boots today. They are lighter than most boots 240g each compared to Predator Pulses 300g and the Vapors are 200g so not far off there. I am also a fan of F50s as i have also had Predators and prefered Playing in F50s. Vapors maybe incredibly light but the upper is extremely thin not helping when tackling or trying powerful shots. I am also a big fan of Mizuno Morelia Waves and am getting a pair in the post soon- They are almost as light as vapors but have a thicker upper- good for shots and feel etc. What do you think???
