Ultimate Performance Advanced Support Plus Insole with F3D
Skip until brand discloses F3D coating composition and PFAS status.
The brand does not publicly disclose what the F3D coating is or whether it contains PFAS. Insole material and coating composition remain unspecified by the brand.

What Ultimate Performance Advanced Support F3D is made of, ingredients and materials
The brand describes the insole as a proprietary polymer foam or gel layer with an F3D 'coating' or technology layer, but the exact polymer type (EVA, polyurethane, silicone blend, or hybrid) is not disclosed publicly. The F3D component remains undefined in available product literature, making it impossible to assess whether it is an adhesive, surface treatment, or functional additive. Polymer foams used in insoles can off-gas volatile organic compounds (VOCs) during manufacturing and early use, and some gel formulations contain plasticizers that may migrate under heat or pressure from foot contact.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
Vague safety claims only
Uses vague language ("eco-friendly", "clean") without a specific PFAS statement.
Unknown / proprietary coating
A coating is recorded with no disclosed chemistry.
VOC off-gassing from polymer foam
Unknown polymer foam composition means off-gassing profile cannot be assessed. Typical polymer foams release volatile organic compounds during and shortly after manufacturing; adequate ventilation during initial use is prudent until the F3D formulation is disclosed.
Plasticizer migration from gel or foam matrix
If the gel or foam component contains phthalate-based plasticizers or other softening agents, prolonged contact with warm, moist foot skin could promote migration. The proprietary nature of F3D means plasticizer type and concentration remain unknown.
Coating degradation and microparticle shedding
The F3D coating layer is undefined; degradation over time and under mechanical stress (foot pressure, friction) could generate microparticles. Without knowledge of the coating's composition and bonding mechanism, long-term durability and safety of shed material cannot be assessed.
Contact dermatitis or skin irritation
Undisclosed additives, colorants, or antimicrobial agents in the foam or coating could trigger allergic contact reactions or irritation in sensitive individuals. The lack of material safety data makes it difficult to identify potential allergens in advance.
PFAS
PFAS grade of 35/100 suggests possible PFAS presence in formulation; F3D composition silence prevents confirmation. PFAS in footwear components is increasingly documented; this product's refusal to disclose creates material doubt and warrants postponing purchase until the brand publishes F3D composition and PFAS testing data.

The brand's record and disclosure
The brand maintains a product-focused marketing approach but has not published material safety data sheets, third-party certifications (such as Oeko-Tex or similar textile/material standards), or comprehensive ingredient disclosure for the F3D technology. The brand has remained silent on PFAS use in their formulations despite PFAS becoming a standard disclosure point in the footwear industry. No publicly documented recalls or safety controversies specific to insoles have been identified, but the lack of transparency around proprietary coatings limits independent verification of safety claims.
How it compares in its category
Premium insole products in this category vary widely in transparency; some brands (such as Superfeet and Powerstep) publish material composition and certifications, while others rely on proprietary claims without disclosure. The brand' refusal to specify F3D composition or PFAS status places it below industry transparency benchmarks for health-conscious consumers. Comparable insoles often use disclosed EVA, polyurethane, or natural materials (cork, leather) and carry certifications such as CE marking or podiatrist recommendations that the brand does not emphasize.
If you buy it
Air out new insoles in a well-ventilated space for 24-48 hours before use to allow initial off-gassing of VOCs. Avoid prolonged exposure to heat (direct sunlight, dishwashers, or heat sources above 50°C/122°F) as this can accelerate degradation of the foam matrix and potential migration of additives. Replace insoles if the foam compresses noticeably, the surface coating peels or cracks, or if you notice persistent odors or skin irritation after the break-in period. Hand-wash only with mild soap and cool water; machine washing or hot water can damage the proprietary coating and foam structure.
