If the SFX2 is not cushioned enough for you, you probably need something like a Boost basketball shoe from Adidas. I have the Crazylight Boost 2016, and I like it a lot as a tennis shoe. In fact, if you look at the herringbone type outsole and the reinforced toe guard, this shoe even looks like a tennis shoe. The only negative for me is the durability isn't that good on hard courts, but that's something you'll have to expect from most basketball shoes. The Crazylight Boost 2018 should be even better because they addressed problems related to heel slippage that some people experienced with the 2016 model. Another shoe you can try is the Harden Vol. 2. It's a little heavier and more expensive, but it has even more cushioning than the Crazylight Boost and it has a neat customizable lacing system. I wouldn't recommend the Crazy Explosive because the outsole is so thin you won't have that many matches to play on hard courts.
Crazylight Boost 2016 are great, but watch out for heel slip. The little folded fabric in the back is kinda weird against the achilles.
