I would Like to personally know how it effects Zanshin. There is more than one way Zanshin is modified. Partially because the recent upgrades to SAM, certain things are overlapping. Take for instance the Relic pants and Third Eye. Whereas before SAM even had Seigan you could indeed counter under Third Eye with the Saotome Haidate. Now, Seigan makes those pants fairly worthless.
I would like to know whether it enhances Proc rate of Zanshin or has the Ikishoten effect whereas it adds extra TP to a connected Zanshin proc.
Either way these boots are not completely worthless. Albeit you should never WS in anything but Rutter/Hachiman feet. But to use as TP build they exhibit a couple useful stats. Attack+8 identical to Saotome Sune-Ate and Enhanced Zanshin, so if you are like myself and cannot afford to remove Weapon merits from other locations for GK and merited Zanshin/Ikishoten combo, they my be worthwhile. On my Zanshin hits I pull back 26TP, which is quite nice. Makes up for my lack of Accurracy in GK.
I plan to get them just to have the complete set. So don't flame over it LOL. Just SAM drops like rain in my Limbus shell. So whatever.
Also not sure how many of you have done Meripo w/ 3-4 SAM bouncing hate, but might be acceptable for that as well. Not sure, haven't used them for that purpose, but it's possible.
