API has a long tradition in the footwear sector basing its success on a series of ground-breaking products and solutions which provided both improvement and innovation. Examples are the first application of reticulated and expandable polymers allowing for the production of extremely lightweight items with excellent physical-mechanical properties which have been put to great use in sports footwear. The products of API are the following:

- Apilon 33:  vast family of PVC and butadiene-nitrile rubber polymer compounds (NBR), used for extrusion and injection moulding

- Aplion 52: a line of thermoplastic polyurethanes produced by API with excellent mechanical properties, elevated elasticity and superior resistance to low temperatures, Apilon 52 products are the leading materials used in high quality sports shoe manufacturing. Ski boots, ice-skates and football boots are the most established applications for these materials

- Apifive: cross-linkable and expandable products modified with thermoplastic elastomers and rubbers to improve softness, soft touch and matt finish (imitation of vulcanized rubber) with excellent aesthetics

- Apicolor: colour masterbatches based on various elastomers. They are developed to get the best compatibility with the product to be coloured without changing its intrinsic properties
