Very comfortable - but they run a bit on the small end of the scale
So my shoes were starting to lose their memory foam insoles.  And I've turned to after market insoles to extend the life of my shoes.  These are one of the most comfortable I have tired.  They fit nicely in your shoe, and they did so without having to be trimmed down.  I ordered the size 11-12 but they fit perfectly in my size 10 1/2 shoes.<br /><br />I put them in and went on a walk in the evening and immediately noticed a difference.  I then wore them all day today and my feet don't at all.  They have a lower profile than most so your feet don't feel crowded in your shoes.  And the gel padding is quite comfortable.<br /><br />The arch support is perfect for me, but on my left foot it did take a few hours for my foot to adapt to the extra support these arches provide.<br /><br />They are definitely worth a try.  But if you are bordering on sizes, get the larger insole.
