Using these goalkeeper gloves is easy. Just slip them on your hands and adjust the elastic strap for a snug fit. When using, focus on catching the ball with the latex foam palm to get the best grip. Make sure to dry your hands before putting on the gloves to keep them in good condition. As for maintenance, after each use, gently wipe the gloves with a damp cloth to remove dirt. Don't expose them to direct sunlight for a long time as it may damage the latex foam. Store them in a cool and dry place. Also, avoid using sharp objects near the gloves to prevent any cuts or tears.
