We recommend that you only wear your insoles for half a day on the first day. Increase by an extra hour each day to transition. After 5-7 days you should be wearing your insoles for the entire day.
It is normal to experience a little discomfort in the first few days of wearing your MASS4D® Insoles as your feet adjust. This is known as the break-in period and usually lasts for 2 to 3 days.
If your feet feel cramped in the shoes with less wiggle room than you'd like, you need to trim the length of your new insole as described below. Just follow steps 1 to 6.
