The Nivia Purple Football studs feature a synthetic leather upper with a special 3D embossed design on the front, which helps you have better control over the ball and makes it easier to tackle opponents. The shoes also come with a removable sockliner made of a special material called E.VA, which adds an extra layer of cushioning and comfort when you step into the shoes. The lightweight insole of the shoes is pre-molded and made of a special material called soft cushion die cut EVA, which not only provides more comfort but also improves your grip on the ground, making it easier for you to run and change directions.
