Besides giving a very high boost to Poison Resist, Sandstorm Trek also gives a large bonus to Stamina and a substantial cut to stamina drain. Given that these boots have self repair, the ethereal version is superior to the non-ethereal version. However, at later levels (especially in Nightmare and Hell difficulties), Sandstorm Trek pales in comparison to other unique boots, because most characters have far more than enough stamina to sustain them for long intervals of running.

It can be said that this item helps the wearer to navigate, or trek, through those sandstorms with relative ease, as suggested by its bonuses to Stamina.
