What is the CustomComfort Insole made of?
A. The insole is individually machined out of specially tailored densities of Ethylene Vinyl Acetate (EVA). This is a non-plastic material commonly used in the mid-soles of athletic shoes. It is comfortable and very resistant to breakdown. We top off this foundation with a variety of topping materials. Each finished insole is hand sanded to fit into the desired shoe. Q. What kinds of shoes do CustomComfort Insole fit into. A. Any shoe with a removable insole will work just fine. Please remove the original insole and replace it with the finished CustomComfort insole. Some shoes without removable insoles will work as well. The things to be aware of for shoe without a removable insole are: 1. The insole you order should be 3/4 length 2. The interior of the shoe should be relatively flat 3. The design of the shoe should be such that it does not deform the finished insole.
