These work well, but beware of your shoe choice.
My first try with this type of insole. Overall pretty good. They're comfortable enough for walking around. They really boost your heal. Using the minimum amount of boost in my low-cut Puma sneakers, my heal comes almost close to sliding out the back of the shoe. If I wanted to use the additional inserts my heal would definitely not even fit in my shoe. They inserts are a bit narrow for me, but they do the job. No complaints, just sharing my experience. 4 stars.
