Too early to tell
I figured for this price I'd give them a shot.  I generally tend to be like the princess and the pea so things that poke I notice too much to use.  But hey if it helps.......<br /><br />I haven't tried them in shoes yet but so far what I noticed is how ultra thin they are!  In fact I'd forgotten it was a 2 pair pack and while we were inserting them into a shoe one slipped a bit.  So glad!  Otherwise we'd have had 2 in 1 shoe and I'd imagine they'd eventually slip and cause discomfort.<br /><br />I stood with it on carpet before giving it to my husband to try in his steel toes and barely noticed all the things poking on my foot.  I'm a bit amazed honestly I thought I'd step on it and immediately throw them in the trash.  I noticed pressure from the magnets but not pain.  And I was aware of a few of the massage nodes .  Not to the point of discomfort but a slight annoyance.<br /><br />He didn't have to trim, they fit right in his shoe.  He's been walking around for a bit in his steel toe shoes and said it feels like rocks in your shoes.  Not painful but you have to resist the urge to take off your shoe and shake out the pebbles.<br /><br />I cannot say as to if they help or not.<br /><br />But I felt I should review early as the reviews on here are so distorted.  Several of the positives are for die cuts and 90% of the criticals are about the missing pair.  That most likely are not missing, just not seen.  I've never seen anything hide like those boogers did.
