Purely Listed analysis

Wool/natural-input footwear and accessories; feed shows merino/eucalyptus socks and masks, but shoes are mixed-material products. No brand-wide plastic-free claim is assumed; sewing thread, elastic, linings, closures, finishes, and trims still require product-level confirmation. The score is brand-wide: an excellent 100% natural-fiber item does not make a mixed catalog synthetic-free.

What to verify before buying

Confirm the exact product page and care label for fiber percentages, sewing thread, elastic, labels, linings, closures, finishes, coatings, and packaging. “100%” normally describes the main fabric unless the brand provides a full component bill of materials.

Best for

Comparison shopping for wool-based footwear and merino/eucalyptus accessories.

Material risk

Merino wool and eucalyptus-derived inputs are combined with foam soles, rubber, recycled polyester/nylon, elastane, adhesives, and other engineered components. No shoe should be treated as a natural-fiber garment.
