I am so glad I took a chance on these insoles. I have diabetic neuropathy in my feet so they burn almost all day. I was looking for something to be kind to my feet and these insoles are AMAZING. I put them in an older pair of shoes and it was like walking on clouds. I have ordered many pairs of Merrell shoes over the years because they are so comfortable. I even could stand up in them for 12 hours a day at work before I retired. Thank-you so much for making such a wonderful insole for the rest of my shoes.
