I just received the triple density Merrell insoles which I ordered, and they are so comfortable! I wish I had ordered them years ago. The first pair I had lasted about 12 years, and although I can still wear them, I really notice how much more cushioned the new ones are. I wear them in all my shoes, not just the Merrell's, so it must say something about this superior product! It feels as if I am walking on clouds. The job I have requires me to stand on concrete all day long, so these insoles are worth their weight in gold! My feet are not even sore or tired at the end of the day. Thanks again! I will continue to be a regular customer as long as you continue to make these quality insoles.
