Work well
I put these in my work sneakers and really like them a lot.  The are easy to use and easy to trim to the perfect size.  They are very comfortable and don't cause my feet to sweat too bad (a walk 8 to 10000 steps a day at work so I'm on my feet and lot).  They also stay put hen I take my sneakers off.  They have made my ratty old sneakers feel like new ones.  They do really form to your feet and are very comfortable all day long.
