If you are look for a flat soft insert that does not take up much space, this is a good one.  However, I over pronate and while I thought I could do without arch supports in shoes that did not have a lot of room for bulkier inserts, I was wrong.  I ended up getting plantar fasciitis again and had to go back with a more substantial insert - the pain went away, but it is a reminder that &#34;if it ain't broken, don't fix it!&#34;
