Ring of Invisibility is slightly different as its use activated, not command word. However boots of levitation are worded such that they give exactly the same result as you casting the spell on yourself. As such there's no reason for the magic to fade when you remove the boots, until the duration runs out. Of course the 3 minute duration makes this somewhat impractical. Unless you decide thats too 'clunky' and decide that it should just last forever. In which case you need to make another dubious ruling about the magic fading as soon as you remove the item... and yet your 2 dubious rulings are less 'clunky' than my 1 common sense ruling ?
Really, whats the downside of admitting that boots of levitation only last 3 minutes per activation, and then promptly forgetting about it ? Why the need to rewrite the rules for something that probably will never make one lick of difference in actual gameplay?
