the boot reduce the strength of the slow, not duration.

irelia with this mastery, 35 tenacity, 3 enemy nearby and cleanse on will achieve about 89% cc duration reduction. So its close, a 3 second cc from say rammus and fiddlesticks will become about 0.34 second long cc, should they be dumb enough to use those skills on you when you have cleanse on :D
