His socks?

between his foot (feet) and his shoe. It is black and in between the heel part of his foot and the shoe... looks like some sort of padding...?

I didn't mean the racquet, I meant the thing between his foot/heel and the shoe

Its just the sock pushed up

I agree with above. It just looks like the heel of his socks are pushed up more than usual.

You know you've made it big when internet forums start obsessing over the way you put your socks on... 4 years ago.

It wasn't me "obsessing over the way [he] put [his] socks on", it was more of a me randomly watching an old highlight (probably to see the difference/evolution of Sasha's game) and noticing something and not knowing what it was since, as I said, it seemed to me it was some kind of pad lol
