Customer Rating: Summary: Great Practice balls! Comment: I have bought over 20 balls in the last three years, and I think nike finally managed to make a great product for a cheap price. Nike makes great balls but they are really expensive, I practice and play soccer throughout the year, in the rain or dry, and practice balls often lose their shape and the outer layers becomes hard and crumbly. But these balls retain their shape no matter the use, they maintain the pressure and don't get heavy when wet.
