Why I Switched to Foam Tennis Balls
My son's enthusiasm for tennis inspired me to find training aids that would make learning fun and safe. After a recommendation, I purchased these foam tennis balls, and I wish I had them as a child!

They're much softer than regular tennis balls and bounce similarly, making them ideal for developing a proper swing without the fear of injury or excessive impact.

The softer texture also eliminates the harshness often associated with regular tennis balls, allowing for a more comfortable and enjoyable learning experience for young players.
Durability and Maintenance
While they offer a lot of advantages, there are downsides to consider. These foam balls tend to attract dirt easily, significantly more than traditional tennis balls.
Water is a big enemy! Avoid playing with these balls in wet conditions as they absorb water quickly due to their spongy nature.
Regular cleaning is recommended to keep these balls in top condition for optimal performance and a more enjoyable playing experience.
Great for Young Children
My two-year-old son loves these larger, softer balls! Their size and softness make them perfect for his age group.
The reduced impact minimizes the risk of injury or damage to belongings. The soft bounciness helps with coordination and the soft nature reduces fear of injury when used at home.
These balls encourage active play and help develop early hand-eye coordination, making it a valuable tool for child development.
Playing Tennis and Catch
Even my husband and son use these balls for two-person tennis practice. The softer impact made it less concerning that my son could hit me unexpectedly.
One time he accidentally hit me in the face during a game of catch; surprisingly, it didn't hurt at all.
This highlights the safety and gentle nature of these balls, making them ideal for learning and playing games with varying levels of intensity.
Performance and Comparison to QST 36
Despite their soft nature, these balls are surprisingly bouncy and can travel a fair distance. They even carry topspin nicely.
I preferred these to the less bouncy QST 36 felt balls. We transitioned directly from these foam balls to the orange QST 60 balls.
It's important to note the distinction between the foam QST balls and the felt QST 36 balls, which are quite different in terms of bounce and feel.
Conclusion: Are Penn QST Foam Balls Worth It?
These foam tennis balls are excellent for young children learning to play tennis. Their soft, bouncy nature reduces the risk of injury and encourages active play.
While they attract dirt and don't handle water well, the safety and enjoyment they provide outweigh these minor drawbacks.
For parents seeking a fun and safe way to introduce their children to tennis, Penn QST foam balls are a fantastic choice.
