Due to the Zeal item buffs I ran many tests on practice tool to figure out how much move speed(MS) you have and if boots are even needed late game to maintain high move speed. All items were tested on Jinx with a Base MS(BMS) of just 325 and Celerity on.

For clarity Zeal do not equal Runaan's Hurricane in this test but all other Zeal options.
The higher the BMS of the champ the more benefit Celerity + Zeals give you. Jinx is tied for slowest champs in the game.
Berserkers + Zeal(7% MS) = 405
Berserkers + Hurricane(9%MS) = 413

Berserkers + 2 Zeals = 429
Berserkers + Zeal + Hurricane = 436
Berserkers + 3 Zeals = 452
Berserkers + 2 Zeals + Hurricane = 458
2 Zeals no boots = 377
Zeal + Hurricane = 384
3 Zeals = 402
2 Zeals + Hurricane = 408 (now we are getting fast W/O boots)

2 Zeals + Triforce W/O Phage proc = 395
2 Zeals + Triforce Phage proc = 429 (same MS as Berskers W/ 2 Zeals!)
Zeal + Hurricane + Triforce W/O Phage proc = 402
Zeal + Hurricane + Triforce W/ Phage proc = 435 (basically same as Berserkers + Zeal + Hurricane)

3 Zeals + Triforce W/O Phage proc = 418
3 Zeals + Triforce W/ Phage proc = 449 (close to Berserkers plus 3 Zeals)
2 Zeals + Hurricane + Triforce W/O Phage proc = 424 (almost Berserkers + 2 Zeals already!)
2 Zeals + Hurricane + Triforce W/ Phage proc = 455

Notes 1: Phage passive "Rage" should essentially always be active in team fight. 455 MS without boots but plus 5% AS, + 25 AD, 20% CDR, 250 HP all while losing just 3 MS for exchanging boots to acquire Trinity Force is an easy choice.

Notes 2: 250 HP from Triforce, the Life Line passive on PD, 455 MS, still room for IE of course and another item. BT, Mercurial, LW, whatever you choose. I think LW plus a red pot you would have lots of effective HP, sustain(including runes) and TONS of damage.
