LESS PRESSURE MORE COMFORT: Our innovative combination of high-quality materials provide excellent impact reduction and moisture-wicking capabilities for unmatched comfort. Protalus insoles improve alignment of the ankle by 31% when compared to generic stock shoe inserts IMPORTANT BREAK IN PERIOD: Re-alignment of your joints does not happen over-night. For best results, retraining your feet to properly align can take several weeks.  For the first week, we recommend walking on the new insole no more than an hour or two at a time.  Some people experience pain and discomfort, and that is normal.  Full instructions provided with every insole.
