Enum: FootwearMaterialEnum

Primary upper-material of a footwear item — the dominant outer fabric or surface visible on the shoe upper (excluding the sole, which is rubber or synthetic in almost all footwear).

Grounded in Product Types Ontology (pto:) where distinct IRIs exist, and schema:material as the overarching property anchor for values without a discrete pto: IRI. Aligned with ClothingMaterialEnum for shared values (leather, suede, wool).

Three redistribution-relevant uses:

1. Care requirement matching — leather needs conditioning; suede

   needs specialist brushing and waterproofing; canvas is typically

   machine-washable; rubber boots can be wiped clean.

2. Allergen filtering — latex rubber (natural rubber) is a known

   allergen; most modern Wellington boots use synthetic rubber but

   natural rubber is still used in premium lines.

3. Seasonality hinting — canvas and synthetic_mesh are typical

   summer/spring-autumn materials; wool_felt is associated with

   warm indoor slippers. Fragment compiler MAY use material as a

   supplementary UI pre-fill hint (secondary to subcategory-based

   hints). Sorter always overrides.
