Abstract: A new method of making custom fitted products and products made by such a method for improving the fit and comfort of such products. The invention includes incorporating a hollow, sealed envelope into an apparatus, injecting a hardenable, liquid gel-catalyst mixture into the envelope through an inlet, and using a portion of a persons body to apply pressure to the envelope and allowing the mixture to harden while the pressure is being applied. The initially liquid mixture will conform to the shape of the body part which is applying the pressure, and once hardened will provide a product which is specifically shaped to the individual's body part. The product could be a shoe, a safety helmet, protective padding for various parts of the body, handles on tools and implements, and the like.
