No, if you do it correctly. Instead of throwing the gloves in the washing machine randomly, use a suitable goalkeeper gloves wash like Reusch Re: Invigorate Glove Wash. Apply gentle rubbing with your finger to remove the dirt. Rinse the gloves thoroughly so that no soap is left in the gloves. Otherwise, it will pull the moisture and dry out the gloves in a quick time. Hang dry the goalie gloves, don’t dry it under direct sunlight. These processes will retain the quality of the gloves after washing.
