It’s up to your discretion, though be aware that cleats sustain a great deal of wear and tear, so you could be putting your younger child in ill-fitting cleats. After prolonged wear, especially in cleats with cushioning or memory foam, these materials become compressed and are subpar when it comes to shock absorption. That means your child’s feet will pound the pitch as they play, and it could result in foot pain or poor foot alignment that may cause other orthopedic issues.
