You still really want infused leather boots, not like you have anything else to spend the skill points on as psi.
Without crafting skills you might be tempted to put them into evasion and dodge
.
Stealth psi can handily make do with store-bought/looted black leather and black tabi, but I agree that's a worthwhile consideration.
If done right, a "finished" full psi character would no doubt have ideal levels of all four psi disciplines (max for the damage workhorses; sensible plateaus otherwise), fairly high stealth, enough hacking to pass the most difficult checks, reasonably high Electronics, Tailoring, and Biology (Biology perhaps only to 70), and ideal plateaus of any two social skills. Sacrifice one if Lockpicking is also desired.
Honestly, you could probably squeeze them all in without losing out on anything, Lockpicking included.
