If I'm not mistaken Bibby debuted them during a televised game before anyone, including Penny.
I tried to do some reserach. The Final Four took place between March 29th and March 31st 1997. Bibby first wore them on March 29th and then again on March 31st.
Penny wore them for the first time on April 4th at Madison Square Garden.
So Bibby did wear them first. Penny wore them for 14 games, 9 regular season and 5 playoff games. He wore 3 different colors (Neon Royal away, Black away, White home), although the black colorway, which he allegedly wore at Washington is still somewhat a semi mystery, since it was never 100% sure, if the shoe was black or not dark blue.
He wore the neon royals at the Knicks, at the Bucks, at Toronto, at Cleveland and during the 5 playoff games.
He wore the White ones during the home games against Chicago, Boston, Detroit and Miami.
He wore the black pair at Washington.
I watched game 5 against the Heat recently and the Magic had a legitimate chance of winning that game, if Penny would have gotten more foul calls and made all of his free throws. There were a number of questionable calls, where Mourning blocked Penny and the refs did not call a foul, but I guess that was just the way the 90s games were played, just straight battles!
