A method of shoe lift modification is called honeycombing. This is a technique pioneered by American Heelers Orthopedics (www.orthopedicshoelift.com), which ensures the added lift is up to 50% lighter and more flexible then a basic shoe lift. The way that this works is hollowing out the shoe lift in layers before it goes into the shoe. While keeping its stability and durability the reduced mass results in a shoe lift that is much lighter and more flexible than its compatriots. Most of our customers who have tried this lift technique for only an additional charge of $19.99 love it and prefer this method of shoe lift modification. The honeycombing technique can be applied to a shoe lift in any shoe style or brand.
