Off the shelf - there used to be some thinner Chinese pads which were fine in stock form.
I am still using the modded Stax 009 pads on them. Sound really good.
The damper foam ring around the drivers also changes the sound very much. One more variable to play with, together with the pads.
Try leather pads that are shallow (not more than 20 mm thick in the back), have at least 70x50 mm inner opening and eventually are perforated on the inner side.
I used the leather version of these for the D9200, but needed to trim the inner foam (same mod as with the 009 pads).

If you can order more easily from Brainwavz, you can try these:

They are rather high at 30 mm and have memory foam padding, but the perforated inner side may help.
Also, when they get warm, all memory foams will contract, changing the height, but also the density, which is why I don't like them. I prefer normal open-cell or closed-cell acoustic foams.
In the worst case you can mod them
. Usually the mod consists of trimming off about 30% of the internal foam mass.
The Stax 009 (and 007) earpads are far easier to mod, since you don't need to break the sewing, just fold them out - and you can also leave them alone.
I am still using 009 pads that are 10 years old... so yes, expensive, but gets balanced out on the long term.
Sheepskin is also easier to take care of with leather care products. With proper care, they can last a decade or more...
Also, Stax is using very good foam, good for acoustic reasons, not only for comfort reasons (like memory foam).
