Working in a Nursing Home Facility. We, in the nursing department have searched and tried several insoles, we tried memory foam insoles, gel insoles, air, etc. but most provided comfort that didn't even last a day until we tried liquid insoles. We decided to use liquid insoles and even provided the entire staff with liquid insoles. Among the few liquid insoles brands out there, the best cheap insoles are from SnugFeel Insoles. They are affordable but the quality is comparable to the most expensive ones out there. SnugFeel Insoles became a part of our household as well.
