The IDEASTEP XD-663 uses three materials for three different jobs: suede for the footbed surface, EVA for cushioning, and a PP shell for structure. This combination gives the insole a comfortable feel without relying on soft foam alone.
For wholesalers and footwear brands, the XD-663 offers a practical construction for comfort-focused and support-oriented footwear programs.

Three-Layer Construction
Suede Upper
The suede upper provides a soft surface under the foot and gives the insole a clean, refined appearance. It is suitable for everyday footwear where both comfort and appearance matter.
EVA Middle Layer
The EVA layer provides cushioning between the foot and the rigid base. Its lightweight foam structure helps absorb impact and creates a softer feel during walking and daily use.
PP Shell
The PP shell forms the structural base of the insole. It helps maintain the insole’s shape and provides support around the arch and heel areas.
Together, the three layers create a simple balance of surface comfort, cushioning, and structural support.
Where Can XD-663 Be Used?
The XD-663 can be considered for:
- Walking shoes
- Casual footwear
- Comfort footwear
- Support-oriented footwear
- Orthotic footwear programs
- Private-label insole projects
The final configuration should be selected according to the footwear design and intended application.

Why It Works for Wholesale
The XD-663 uses familiar footwear materials in a straightforward construction, making it suitable for different B2B product programs.
For wholesalers, distributors, footwear manufacturers, and orthotic suppliers, it can be used as a ready insole platform for bulk sourcing or further customization.
OEM and ODM options can be discussed for requirements such as branding, packaging, material selection, and structural adjustments.
