IIRC the prosecution had a witnes on from Aris, the maker of the gloves.
I learned a valuable lesson from the OJ case. Shortly after the glove incident I was prosecuting a man for rape. One item of evidence was a white sock that was found at the scene. When the defense put the defendant on the stand to testify, in my cross examination of him I had him remove his shoes and I placed the sock up against his foot to show that it fit. I did not try to have him put it on. One thing they taught us in trial advocacy class was to never let a defendant handle the evidence. As anyone knows, you can flex muscles, etc., to get an article of clothing to not fit correctly.
OBTW the defendant was convicted and got 30 years for the rape.
It was an amazing case.
