I find tons of slow practice helpful as well as using the 2nd finger as a pivot for the hand rather than the middle.
This is one of those Etudes that is just extremely unforgiving. It is possible to play it without effort even on heavy grands but it is very difficult if there are any tensions or inefficiently coordinated movements in your technique. If your thumb is a bit tense when the other fingers play, you are dead. If your 2nd finger is a bit tense when the other fingers play, you are dead. If your 3rd finger is a bit tense when the other fingers play, you are dead. If there are tensions hindering any of your fingers from moving efficiently, you are dead. You get my drift. You need to have a very supple hand and arm at all times, and that means having relaxed shoulders, upper body, neck and even legs too.
