I've seen mercurial vapor II HG on sale on the internet and they look a little different from the vapor FGs. Well the only difference i see is the bottom or sole of the shoe. The colour of the bottoms are different.
I'm wondering if that's the only difference between the FG and the HG boots.
Are the HGs really the same as the talaria? or the same as the FG except for the bottom?
HGs are a bit cheaper than the FGs too

Really appreciate it if someone could tell me a little about this.

thx in advance!
