You don’t need any special soccer freestyle ball if you want to play soccer freestyle. When you play freestyle soccer you use a regular football size 5. If you are young and not very tall, then a size 5 ball might be a little to big for you. My advice to you if you are young and short: Use a size 4 ball. Then when you grow and get older switch over to a bigger ball.
Monta have created a soccer freestyle ball that is only made for soccer freestyle. Many soccer freestyle players use it and some of them thinks it’s the best ball for soccer freestyle.
Some other of the most popular balls for freestyle soccer is the Adidas Teamgeist World Cup ball and the Nike Tiempo Legend ball. Both those balls give you a better touch and makes it easier to pull of the tricks.
