Ouch!
I tried one in only one shoe to compare with the other foot. I made sure to position it correctly. Instead of feeling extra cushioning, it felt like a wad of paper. Immediately upon walking I was uncomfortable. However, I thought I needed to get used - soften it up a bit -so I kept it in. After a short while the discomfort turned to pain and all I could think of was stopping somewhere to take it out.  Maybe I got a defective pair with solidified get or something but not going to try it again. Even after taking it out, I went around limping for the rest of the day.
