Went to Wally world and stepped on the 'tester' and bought the inserts recommended. I have nerve damage on the bottom of my right foot - and those inserts work wonderfully for me. I can't walk barefoot or without the inserts, or I feel it. Plus, I've discovered that if I haven't been drinking enough water, my foot will start hurting even with the insert. So I make sure I drink enough water, wear my inserts and I'm good to go. I work in a job where I'm on my feet a lot during the day, so its a blessing to be able to do it without all the pain. Everybody is different - had the inserts not worked, then a custom shoe store would have been my next stop. My DH paid over $300 for a pair several years ago - and I didn't want to go that way unless I absolutely HAD to....
