Just like insoles, any change in the support your feet receive will take a little bit of time for your feet to adjust to. We recommend only wearing your new footwear for a few hours at a time for the first few days to allow your foot time to adjust to the new arch support. If you wear arch support insoles or orthopedic footwear already, your adjustment period to your new footwear may be shorter. If you don't wear arch support insoles or orthopedic footwear regularly, it may take several days to a week of occasional wear for your feet to fully adjust to the new footwear.
