If you plan on using this ball in games, check with your league to see what size of ball is used for different age groups. If not, buy which ever ball you’re used to or like the best.
Check the material of the ball to be certain! Many manufacturers sell synthetic cow leather soccer balls, and it may not be obvious at first. Be sure to read in depth and the fine print as well. You may have to get custom made soccer balls out of cow leather.
Is the ball waterproof? Most leather balls don’t come from the factory as waterproof, while sometimes the manufacturer ads a protective coating to prevent this.
Does the ball come with a warranty just in case if it goes flat or deforms shortly after you purchase it?
Lastly, ask your friends and teammates! Which ball do they prefer and have used over the years. You’ll be sure to have a great soccer ball and a great time!
