Essential Gear

Basketball Shoes
High-top or mid-top shoes provide ankle support on hard courts. Look for non-marking rubber soles and good cushioning in the heel and forefoot.
Est. $40 – $120
Basketball
Size 5 for younger kids, Size 6 for U12 girls and middle school, Size 7 for older boys. Rubber outdoor balls are fine for driveways; composite leather for gym use.
Est. $20 – $60
Athletic Shorts
Loose-fitting shorts with a comfortable waistband. Most leagues provide game shorts; these are for practice. Moisture-wicking fabric keeps players comfortable.
Est. $15 – $35
Athletic Crew Socks
Cushioned crew-length socks reduce blisters and provide extra comfort on hard floors. Avoid ankle socks — they offer no protection under high tops.
Est. $8 – $15

Parent's Cheat Sheet
What just happened?
Official Wording
Illegal personal contact that disadvantages an opponent.
Parent Translation
Your kid pushed, grabbed, or bumped into the other player. 5 fouls and they're out for the game (some youth leagues allow 6). Common at every level — even NBA stars foul out.
