actually the 90's version worked well. they were pretty ugly, and as far as i am concerned these Nike glasses are even worse looking. i feel this is more of a case of a conglomerate finding something old they that thought was dead and pacing it off as their own. sure i bet they reverse engineered them and made them better, it's been well over 10 years and technology is far superior now then in the 90's. maybe i just hate Nike and will never wear/use one of their products. either way, they are ugly, will most likely cost around $500 and not work nearly as well as their concept ad states. to quote Dennis Miller "That's just my opinion, i could be wrong."
