While, I can‘t speak for others, I have ventured into the Kobe line ever since the 1s and have always been a fan of the low cuts, specically the 4,5,6,& 8s. They were light, strong, flexible, and very responsive to me,
I eventually bought the Xs as my older models have all worn out, and found the Xs to be rather disappointing. The Xs lacked responsiveness by a large margin and felt heavier on feet. It was stable, but the sole was just too rigid.
Copped the BL XIs and was a lot more impressed by the insole and flyknit upper as it made the shoe more flexible when compared to the Xs.
In any event, I would say that the XIs are better than the Xs, but if you are hoping for something like the older low cuts, you won‘t get it.
The main thing is to try for yourself as I did. Those vids online are mostly videos to pump up the products.
