Put simply, latex is a type of rubber. Natural latex is a resin, or milky liquid, typically obtained from cuts made in the trunk of a tree called a rubber tree. Synthetic latex is produced from petroleum derivatives.

Latex foam is a product made from synthetic latex, natural latex, or a combination of both. Various additives are used in its production to obtain different types, hardness, and densities of foam. Latex foam is commonly associated with comfort, and it is widely used in the production of insoles and other components for the footwear industry, as well as in mattress manufacturing.
