``POLK'' is made using ``injection molding'', which involves pouring heat-molten material into a mold, and features a unique tabi-like design.
The hardness of each part is changed by adjusting the material composition, so the upper footbed is soft and cushioned, and the outsole is resistant to abrasion and has excellent durability.
