"Amateur runners" is an extremely broad collection of people. Everyone from someone training for their first charity 5K to those who run multiple marathons a year can fall into this category.
Some amateur runners definitely spend $250 on shoes, either because they have so much money that $250 is basically the same as $70 to them or because they are very serious amateurs.
