ALO Recovery Mode: Multi-material Integrated Footbed
The ALO Recovery Mode footbed combines an EVA heel section and an ETPU forefoot section to meet different hardness requirements. Both materials are pre-foamed and separately compression molded before adhesive application and heat-press bonding. A pre-treated terry-cloth cover completes the integrated construction.
The challenge
Bonding EVA and ETPU into One Integrated Footbed
The key challenge was to achieve a secure bond between the EVA and ETPU sections while maintaining a smooth, natural transition at the joint.
The terry-cloth cover also needed to maintain consistent colour, surface appearance and hand feel across the finished footbed.
Our work
What We Did
We focused on material selection, separate molding, bonding and textile integration to develop the multi-material footbed as one component.
Material Zoning
The forefoot uses ETPU sheet material, while the heel section uses EVA. The two materials are selected to meet different hardness requirements across the footbed.
Pre-foaming & Compression Molding
Both EVA and ETPU materials are pre-foamed and then separately compression molded to achieve their required shapes. The molding process forms the final component geometry without additional foaming.
Adhesive Heat-press Bonding
After molding, adhesive is applied to the EVA and ETPU sections, which are then joined through heat-press bonding. This creates the integrated footbed structure, with attention to bonding integrity and a natural transition at the joint.
Textile Bonding & Quality Inspection
A mold-resistant and antibacterial-treated terry-cloth cover is bonded to the footbed. Final checks focus on colour consistency, surface appearance, joint transitions and overall hand feel.
Result
The Result
The result is an integrated multi-material footbed combining an ETPU forefoot and EVA heel section, with both materials separately molded and bonded into one component. The finished construction features a pre-treated terry-cloth cover, with attention to bonding integrity, surface appearance, colour consistency and overall hand feel.
In the finished shoe: ALO presents the Recovery Mode Sneaker as a recovery-inspired footwear product. Our focus in this case is the integrated footbed construction, combining different materials and molding processes within one footwear component.

FAQ
Common Questions
What factors matter when combining EVA and ETPU in an integrated footbed?
Material hardness, density, thickness and bonding compatibility all influence the final construction. The right combination depends on the intended footwear application and desired underfoot feel.
How do material hardness and density affect footbed design?
Hardness affects firmness, while density influences material weight and cushioning characteristics. Both should be considered when selecting materials for a specific application.
Can different foam materials be combined in one custom footbed?
Yes. Materials such as EVA and ETPU can be combined in different zones to meet specific cushioning and support requirements.
What should you send us for a similar footbed?
The insole outline, size range, material zoning and hardness requirements, material benchmarks, textile specifications, bonding requirements and any required component or finished-shoe tests.
