Foam Baseball

Foam baseballs are training balls, not league game balls and not futsal. Kid packs such as Franklin’s MLB-licensed foam are official-looking size with a squishy core for indoor catch. Coach packs such as GoSports sell regulation-size foam by the dozen with limited flight. Pitching-machine foam is a different product: Tater-style balls target a 5 oz regulation weight so they do not climb off the wheels the way 3.6 oz foam does.

• Kid ~70 mm soft foam versus regulation-size training foam
• 5 oz machine foam versus lightweight backyard foam
• Seam and stitch look for tracking versus smooth toy foam

Read ounces and diameter, then skip dimpled pitching-machine dimple balls if you wanted a squishy backyard toy, and skip leather game baseballs if you need indoor-safe foam.
