That's how it was working in most wealthy countries, where tariffs were generally low or very low.

I don't see why it must continue to work that way in the USA with 50% or 100% or more tariffs. If Footlocker wish to charge double the post-tariff price, that leaves room for a competitor to change double the pre-tariff price.

(Or double the pre-tariff plus a tiny bit, to account for the increased cost of insurance, theft etc.)
