Yes jax can use all of these boots if the situation warrants

Mercury - 99% of the time picks these (if you are CCeated you cant deal dmg) if they have so much magic dmg pick these too.

Tabi - if they have tons of physical damage or champs dependet basic attacks (vayne,yi,trynda,ect.)

CDR - If you want to do more damage or need to spam your Q or E these are your boots.

Mobility - If you need more mov speed to initiate.

Swiftness - If you need more mov speed in combat.

Berserker - IF they are so much tank and you want to abuse of the damage of your BOTRK

Sterak´s gage - Sterak synergy very well with jax´s R active making jax inmortal + the extra AD help the sheen to do more damage.

Dead man´s Plate - If you need more mov speed to chase or initiate + make you more tank

Warmog - Synergy 100% with your R active making jax a champ with HP + Armor/MR

Rightous glory - As the warmog synergy well with your R active + the movility to initiate/chase

Spirit visage - If they have some magic dmg and you want to maximize your lifesteal + CDR

Banshees´s veil - if they have magic damage + CC/hard pocke

Sunfire cape - Jax is always on your target so he can deal all the damage of the sunfire cape

Locket of the iron solari - If your team needs MR and nobody cares there you are :/ + CDR

LVL 1 E because you start on the golems smite+AA stun---- stun ends and you press E dodging some golems AA and stunning at the end---- your golems buff have 5 charges at the end of the stun and the golems hit you with 1 or 2 AA only ;) .

LVL 2 and 3 W because your use the W to reset AA. less cd--More resets--more golems buffs stuns, and the Q animation is much longer than the W.Se

MAX E - If you want to dodge more AA maybe versus vayne,trynda,yi,ect
