Very Disappointed
I am very disappointed in this product.  I have used similar gel heel insoles for three years and wished to get another set so I would not have to move them from shoe to shoe.  On the first day of use, they seemed fine, but by the end of a short work day (minimal walking), I noted (prior to removing them) that two areas had cracked and separated in the left shoe and two areas of the right shoe heal were cracked, but not separated.  Fortunately, I had purchased them on Amazon so the seller issued a refund after I sent back the item.  I only gave them two stars because they were comfortable for that one day.
Rating: 2 stars
