TBH, buying footbeds separate seems like an upsell when you are in the store. If their position is the skate would be best with it, the skate should come with it, especially as you get to the higher price points.
when my son was in youth and junior skates, the Pure associate would automatically bring over Superfeet and try to upsell them. So a parent is buying $200ish skates and here comes a kid telling them, “they really should get these because the stock footbed isn’t that good”, by the way, that adds another 25% to your total.
