What you actually need
Good trainers ($80-120) are where the money goes and where it matters most. Your child runs in them almost daily. Cheap shoes break down fast and cause injuries. Invest in a real running shoe from Nike, Asics, Brooks, or Saucony.
Racing flats ($60-100) are the second purchase, but only for kids 12 and older. Younger runners don’t need them—trainers work fine for 5K races. Flats are lighter and faster, but require some baseline running fitness to use safely.
Cold weather kit comes next: thermal tights or leggings ($30-50), a long-sleeve moisture-wicking shirt ($25-40), gloves ($15-20), and a beanie ($10-15). Cross country runs through November, so you’re buying for October chill and November cold. Regular cotton sweatpants and hoodies don’t work—they hold moisture and make kids miserable.

Used gear notes
Facebook Marketplace and Play It Again Sports sometimes have used trainers, but inspect them carefully. Look for compression in the heel and forefoot—if a shoe is packed down, it’s near the end of its life. Racing flats wear out quickly, so buying new is usually smarter. Cold weather gear is fine used.
What you can skip
Skip compression gear unless your kid has a specific injury. Skip specialty hydration packs—kids carry water bottles or stop at aid stations. Skip expensive race kits. Regular running clothes work fine for 5K races.
