Riot, stop doing bad things. Save the booties.
Instead of nerfing
, try buffing

As things are, CDR is intrinsically a valued stat for pretty much any champion; this means CDR boots will always be valuable. Meanwhile, Swifties are popular at the moment because of the over-prevalence of slows in the game. Not because they are intrinsically better than all of the other boots in the game. Maybe lower the value/duration of many of the slows or possibly remove all of the unnecessary slows (of which there are a LOT) in the game, though this would be a much more complicated answer.
Tabi often isn't worth being useless if you're melee and unable to touch a ranged champ, or unable to engage or kite as effectively. Tanks usually don't need it because they already have enough armor and will often be engaging on the ADC for their team, and they are the prime candidate to be using this item. Not to mention that many times an ADC will have a much higher priority than autoing a tank for 10 seconds. It does happen, but considering ADCs are in every single game, this is a surprisingly situational item.
Merc Treads were over-nerfed. The tenacity is near-useless now. Either remove it and buff the MR, or rebuff the tenacity (the right answer).
For mobis, have the MS decay when you enter combat, and ramp up the longer you're out of combat (starting after the last tick of damage either dealt or received by any source to or from you.
............. wait...

I guess when you can afford it
isn't viable on a lot of champions. Well it is, but you won't find yourself wanting it on a lot of champions.
