Performance Review: Jordan XX9

Some have called the Jordan XX9 the most technologically advanced Jordan shoe ever. From the spec sheet alone, they’re probably right. With a completely new woven upper, unlocked Zoom in the forefoot and Flight Plate moderator, the XX9 looks and sounds as good on paper as any shoe.

But, as we’ve seen with models like the KD VI Elite, packing a bunch of tech into one shoe doesn’t equal great on-court performance. The XX9 breaks that mold though, as Jordan Brand has unleashed a performance monster, and natural successor from the XX8.

Fit
The biggest technological innovation in the XX9 was the Flight Weave upper. Designed to provide a custom fit while retaining strength during dynamic movements and giving engineers the ability to weave fibers tighter in high wear areas, it conceptual roots lie in Flyknit and Hyperfuse systems. You’ll find a tighter weave where more support is needed and a more forgiving weave in the rest – not unlike Flyknit. But where Flyknit uppers have a tendency to leave gaps when the shoe flexes, Flight Weave is hugging the foot at all times.

Flight Weave is miles ahead of both of those textile technologies, and is one of my favorite uppers I’ve tested recently (along with the adidas’ Techfit-based Crazyquick 1 and Under Armour’s Clutchfit Drive). For comparison’s sake, it has more structure than the Crazquick 1 and fits closer to the foot with less shifting while moving around than the Clutchfit Drive upper.

You can lace the XX9 up super tight from to toebox to ankle, and the fit is impressive. The upper fully hugs the foot and lockdown is vise-like. The internal heel counter provides good heel lockdown and I did not experience any shifting anywhere on the interior.

Heel-Toe Transition
One major outsole change from the XX8 to the XX9 was the skinny bridge connecting the forefoot and heel. The XX8 was a true decoupled outsole – the heel and forefoot were independent parts – and that usually means transition isn’t as smooth. The connector on the XX9 remedies that some, but I wouldn’t consider heel-toe transition to be a strong point for the shoe. It gets better as you break it in naturally, but the large gap between heel and toe plus the slightly higher feel makes the ride less smooth than some other shoes.

For what it’s worth, I had been playing in the Clutchfits, which are as smooth as it gets, so the difference in transition may be more apparent to me than you.

Cushioning
The XX9 drops the heel Zoom unit and uses standard Phylon. Honestly, it probably plays a little better and more stable this way, though I thought the heel Zoom of the XX8 was just fine. You’ll get good impact protection and a consistent feel in the heel.

I was a little disappointed in the lack of responsiveness of the forefoot unlocked Zoom. It’s not bad at all, but didn’t seem as bouncy as the XX8. This is because the Zoom bags have been recessed slightly into the midsole, so as to avoid the popping issue that plagued so many pairs of the XX8. The Zoom bags have also been laid horizontally, but I didn’t quite notice the energy return that I did in the XX8.

Since the Zoom bag extends so far up the forefoot, I felt like there was a little dead zone right at the toe where the top flex point was. It wasn’t anything major, just an odd feel to go from Zoom to straight midsole at that specific flex point.

That is all a little nitpicky though, because the responsiveness is still very good. As far as court feel goes I prefer my shoes to ride a little lower to the ground, and with the Flight Plate/Zoom combo there’s a little more midsole bulk than I’m used to. The upper fits so close to the foot that it feels a little funny to have that substantial of a midsole there. Support is fantastic with the sculpted Flight Plate providing plenty of midfoot structure while still remaining flexible. Overall the cushioning setup is very good, if not great.

Traction
The outsole features anatomical sculpting in the heel and forefoot, and uses a full-lenth vertical wave pattern with some recessed horizontal sipes. The courts I typically play on are usually average to slightly above average in condition and I’ve had no traction issues. I’ll still get the familiar squeak on quick pull-ups.

Materials/Durability
I had no issues initially with the XX9. I wondered how the woven upper would hold up when getting stepped on and pushed to the limits on court, because it is softer than I had expected. But I’ve put it through several league and general pickup games, gotten stepped on, and have seen no signs of wear. The build itself is high-quality, free of glue marks or loose strands on my pair.

I expected them to hold up for months, until just yesterday when I was playing in a competitive league in central Indiana. As I unlaced after the win, I realized one of the eyelets – which are simple loops that attach to the midsole – ripped out and left me without a proper way to lace them. Back to Nike they go for a voucher.

With a price tag of $225, I was expecting the Jordan XX9 to blow me away. It’s got the lineage of 28 other shoes riding on it, and is the flagship model for the entire brand. So was I impressed? Yes – the Flight Weave upper is one of the best I’ve played in, and the shoe is great from a comfort and support standpoint.

Was I blown away? By some aspects, yes. I tweeted after my first couple of runs that I was kind of underwhelmed by the XX9 and a lot of that is tied to the lack of responsiveness underneath and average heel-toe transition. But the responsiveness is still above average and the transition improved some with multiple wearings, and I really do like playing in the shoe.

If you have the funds and are a serious hooper, it’s certainly worth a try. I feel like I have undersold it, but I feel that it really is a great shoe – one of the better shoes of the year.
