1.Material Preparation:
High-quality PU or Hi-Poly foam sheets are selected and cut to standard sizes based on shoe lasts.
2.Heating & Forming:
The foam is heated to a controlled temperature to soften it, then placed into precision molds under pressure. This heat-pressing process creates a custom-molded shape with arch support and a contoured heel cup.
3.Cooling & Shaping:
The molded insoles are cooled to lock in their three-dimensional form and ensure long-term stability.
4.Finishing & Trimming:
Excess material is trimmed, and the surface is sanded for a smooth finish.
5.Fabric Lamination:
A breathable top fabric is bonded to the foam base to enhance comfort, moisture-wicking, and durability.
6.Quality Control:
Each pair is inspected for shape accuracy, cushioning, and odor resistance before packaging.
