Or can they usually be handed down to a younger sibling/sold/given to a friend etc?

I swear my kids destroy shoes, so a lot of them become play shoes and I have to buy shoes every season for my youngest. Shoes are so darn expensive, I wish we could get more use out of them! Of course, we only have 1-2 pairs per season, so that could have a lot to do with it, since they are getting so much daily use.
