Shoes that retail for $120-$150 don’t cost $100 to make. Normal shoes cost like $20 to make. The rest of the costs are transportation, warehousing, marketing, etc. Also remember that retail takes a 25-35% cut. I would expect a shoe that costs $200 to make to retail for at least $400.
My point is that the hypothetical $200 difference between a pair of shoes made in the US, and somewhere else, is not going to go to the folks making them.
