i have been on ***** end of buying a pair of fake gl3 and it was very very clear they were fake in hand. shape was horrible, the left and right toe box did not match at all. pics do not look that bad to me but in hand should tell you pretty easy. not too mention the materials were garbage on the fakes which says a lot because asics are not known for great materials. the materials on fakes i had were pretty much wal mart qaulity. its hard to say this thread is whack etc. over the internet. not every shoe has identical threads regardless is they are the same pair. i have doubles of a few gl3/5 and there are slight differences in them.
