I was wondering the same thing

They did have Vapor but still used numbering system even with RF attached to it.The even dumber model name? From 1 to premium to 1.5, could Nike be any more unimaginative? Pay Alcaraz and Sinner more and use their names? Sinnerman? Zoom Carlitos? I mean they had RF and milked it for years.
People were asking for GP, they have sinner behind them, who cares if it is 1.5 or 2.0? They’ll sell because people wanted GPs and because of Sinner.

That's my point, instead of capitalizing on the athlete, Nike won't let most athletes outshine the brand. The model name GP Challenge Pro/Premium/1/1.5/XXX or the Vapor 12 vs Vapor 12 Hypersmash, does not help with model differentiation or recognition. You'd think Sinner and Alcaraz have enough slams/titles and hype to warrant that their own shoe like Rafa and RF?
lol.
I am actually actively looking for an alternative, for the exact reason that he is now wearing it.

Only difference I can spot is the last eyelet on the medial side being TPU, not the lacing loop thing like the 1s. Maybe that’s the goal? Seems like it might work but it’s also Nike so like maybe not

I had the opposite experience. The GP Challenge 1 are very comfortable for me, way more so than Vapors. I’m significantly overweight too, so I am putting more stress on the shoes than the average player

Zoom air is pretty firm and tends to be more about energy return than shock absorption for me.
I agree.I had the opposite experience. The GP Challenge 1 are very comfortable for me, way more so than Vapors. I’m significantly overweight too, so I am putting more stress on the shoes than the average player
I'm the opposite, I'm pretty skinny but that was sort of my determination. These shoes are great if you're a little bigger because you have more mass to create potential energy that the shoes can then use.
My feeling is the same with the hypercourt pinnacle.

I am currently using the NikeCourt Zoom GP Challenge 1 with my orthotics as my current casual shoe. The only flaw I feel is the tongue is a little narrow so when i wear them with no-show socks the upper corner presses against my foot (See photo below). I have no issues with crew socks and I'm actually thinking of trying them on court. I hope they keep the width of the 1.5 and fix that flaw.

Looks like this is clay-soled
My hot lava and psychic blue pairs of the GP challenge 1 have a traditional top eyelet rather than the outrigger lace loop, and they feel MUCH more secure on my skinny ankle walking around the house. Hopefully they stay tight with play. Already liked this shoe despite having to re-lace a few times on the court. Even if the only change is the lacing, they could be a nice improvement if you had heel slippage before and liked the rest of the shoe.

Wow. So I guess I bought one of the older models without the inner top eye loop.
Wait, do yours not? I was surprised since TW takes live pictures as far as I know, and their pics show the loop. I got them from another retailer (sorry TW) and was surprised. They do seem to wrap around my ankle a bit more, but they need a bit more break-in, so I switched back to my slate gray 1s when hitting today. It's not significant heel slip, just that the lacing doesn't quite wrap my ankle snugly in the front, and I feel like I'm either cranking down on the laces ALL the way just to have them loosen up or. I have quite narrow ankles, so this is a problem in many shoes for me.Wow. So I guess I bought one of the older models without the inner top eye loop.
For context in case anybody cares: I have a low volume and pretty narrow foot with a couple hot spots from old injuries some anatomical things up the chain and went TTS in these. They're roomy in the pairs I've worn once broken in. No irritation except from laces on a spot that will rub in pretty much any shoe that's actually supportive. A low profile otc orthotic and/or double socking or thick socks fixes the heel fit for me, though. I think I prefer these shoes with the stock insole because they're almost too stiff with an orthotic in there, but performance is great either way for me. Might have to modify the front of the ankle collar with a little padding if I get sick of the slightly fussy fit - I was expecting worse with all the feedback, though. Hoping my pairs with the actual eyelet stay secure after some break-in. Just wish they were more durable. The uppers stand up to my sliding, but the outsoles go bald quick on me - still playable though.
Edit: tongue is gusseted on the 1.5 according to a non-US ndc product description. My two with the actual eyelet do not have that. So the eyelet was maybe an in-line change or something that snuck through. The description says more room in the forefoot too...so might not be good for me but might fix the sizing issues folks were having.

That's the white/black colorway, right? I said in my post it was my Lava and Psychic blue pairs. All my other pairs (2 white/black, 1 black white, 1 turquoise, 1 slate gray, all of these are pre-HO25) all have the loop. So the holiday/winter 2025 pairs have an eyelet like the 1.5 does. TW's images do not, so maybe they photographed a sample? Or some pairs do, and some don't? No clue, but I think I like that eyelet rather than the loop for my skinny ankle. Easy remedy on the looped pairs, just annoying I suppose.My GPC1s do not:

Yes, mine were dated for the SU23 original release.
Yeah, it was a pleasant surprise when I opened the boxes. Liked it enough to stock up with the loop anyway though

Can someone sparknnote the technical updates ? At first glance it looks identical to the 1

Toungue is more gusseted which is better for stability, nadals custom shoes has a gusseted toungue and the new medial lacing eyelet

Google search shows the following
Nike Zoom GP Challenge 1.5 (Updated)
- Upper: Improved with a tighter mesh weave, more space in the forefoot, and reinforced medial eyelet webbing for better containment and comfort.
- Durability: Features an "updated toe skin" (medial drag guard) for increased resistance to wear and tear.
- Tongue: A new gusset prevents the tongue from shifting during play.
- Feel: Aims for a more balanced feel, addressing the bottom-heavy sensation some felt in the original.

With the GP Challenge 1, the women's size 10.5 matched my men's size 9 exactly from what I could tell holding them against each other. Meaning the soles, when put against each other, were the exact same.
What I don't know is whether Nike uses the same cushioning in men's vs women's. I could see them being different since the average man is heavier than the average woman.
I agree the new women's black color way looks sharp.

Yeah it's the same width. I forgot to mention that in addition to looking to be the same, they also felt the same when I tried them on.

Interesting design on those top two medial eyelets for hers.

The 1's had clay models in Europe, and there was a women's clay in the US. Hopefully they make some for the 1.5 but who knows, it seems like Nike isn't doing too well financially so maybe they are narrowing their model options.
