Looking at a freeze on the Giants/Cleveland game.
It isn't exactly this shoe:
Nike Air Speed Nubby 5/8 - Men's - Baseball - Shoes - Black/White
But, its similar. Newer version and mid to low top. Interestingly, the U is wearing what appears to be the same shoe in all black but no NIKE on the back -- not even in black lettering. The NFL shoes are studded, and look to have some decent support. They are nowhere near what was posted above; they simply look from a distance like Nike's old turf shoes from the early '90s. I had a pair of those and played a lot of softball and flag football in them until my achilles begged for something better.
