Thermoformed heel counter

The heel counter is the rigid or semi-rigid structural internal part of the heel region of a shoe, responsible for maintaining shape, giving foot support and ensuring the heel remains in place during walking. Traditionally manufactured in rigid leather or reinforced cardboard, modern heel counters are increasingly in thermoformed TPU — a part molded in specific shape that is heated and positioned in the upper during shoe assembly. TPU is chosen for offering a unique combination: rigidity sufficient to provide structure but with adequate flex for comfort, superior durability to cardboard (does not deform permanently with use), moisture resistance (rigid leather deforms in humidity), and capability to mold in complex three-dimensional geometries. Applications in premium sports footwear, safety footwear, orthopedic footwear and high-end formal footwear.
