I can't say that boots reflect anybody's personality. Personally, I love white boots. They're usually more light weight and allow me to utilise my pace more. However, they have no protection nowadays. More players are being paid to wear these boots by the manufacturers as a style of advertisement and some such as Cristiano Ronaldo and Obefemi Martins wear the more lightweight ones for the same reason as myself.
I think it's just typical evolution of the modern game which we're all going to have to get to used to I'm afraid.
