Great topic! Do I have all day, lol! Where do I begin! I'll make it short & sweet.
Basically EVERY Agassi shoe!! Every single one!! But for the topic, I'll post the few I definitely want as priorities!
#1 Nike Air Tech Challenge I!! The original! In the green and orange! Nike, follow your own dang slogan and "JUST DO IT"!!! There are so many of us Agassi nuts on the sneaker forums who want this shoe!! If it came out, like the original (or if you need to, use the II tooling and have a visible air unit. I don't care, if it gets me the ATC I sooner!!) I would buy 3 pairs at retail upon it's release! And one would be used on court!
#1A Nike Air Tech Challenge IV 3/4...sold here not only overseas!! Yes, they released this back about 4 years ago. I was lucky enough to grab a pair from a Nike retailer in Italy. But to release this shoe, in the OG Cerise color way, and not sell it here was downright stupidity idiotic!! Release it again and while you have the Cerise color, also release the "Marina" blue color way (The "Not Ginger" color from the ads back then).
#2: Nike Air Challenge LWP!! In ALL 4 OG colors!! My favorite (which I still have and wear) is the black/dark teal! One of the best shoes!!
#3 Nike Air Pounce! Such a stable fast shoe. Felt like I could track down anything on the court.
#4 Nike Air Zoom Beyond (The FO colorway). Had 2 pairs and LOVED them!! Such a supportive shoe!
#5 Zoom Challenge (the Olympics and US Open shoe). Awesome under foot cushioning and the carbon weave at the back in the blue with his "A" logo... AWESOME!!
These are the ones I want to see return before any others. Nike, once you see just how well his '90 Challenge Court clothing will sell (and believe me, it's gonna sell like HOTCAKES) you better keep doing it and release some shoes with the next launch!!!
Oh, and also, Reebok, redo the Pump Court Victory. Still have my 2 pairs of OG colors of the retros and one of the II version. These need to come back as well
And lastly, All of Guga's Diadora high tops!
