I used to be a runner until I started having problems with my feet, mainly plantar fasciitis. Many yrs ago there were inserts called "Phase 4 orthotics" that were sold on TV infomercials. They helped me greatly. Those don't seem to be sold anymore as I can't find them anymore, but these Natural Foot orthotics seem to be very similar.
If you are new to these, it takes a few days to get used to them. At first it might feel like you have golf balls in your shoes. That's because your arches have collapsed. They inserts slowly reshape your feet to the way they're supposed to be. Wear them just an hour or so the first day, then gradually wear them for longer and longer day by day. Within about a week you should be able to wear these full time. I love these. No pain anymore in my feet.
These seem to be the same exact inserts sold at that "Good" foot store nationally, but at a fraction of the price. I highly recommend them.
