Too thick in the toes to use in most shoes or sneakers.  Works well as replacement inserts.
I have had Plantar Fasciitis for many years, and had great hopes for these.  Unfortunately, they do not work in any of my shoes and only one of my sneakers because the toe region is too thick.  They do improve significantly the stress on my heals, however, so if you have shoes that are a size or two too large, these may work wonders for you.  I did have a few hiking shoes which have their own inserts, and when I replace those inserts with these, I have a winner.  These are in most cases a significant improvement over the removable inserts that came with your shoes.  And should be bought primarily with that as the target use.
