M 13 identifies a selection, not every audience
Although the title addresses men and women, its selected suffix is M 13. Confirm the retailer’s meaning and corresponding measurement rather than assuming it is a women’s 13 or a universal unisex number. Black is the listed color; no width, upper material or closure specification is supplied.
Treat indestructible as advertising
No shoe is immune to wear or damage. The advertised puncture-proof and slip-resistant descriptions should lead to requests for appropriate model-level documentation, not home tests with nails or slippery floors. If that information is unavailable, compare a product whose required properties can be established. A lightweight claim also needs a stated size and weight before it can support a fair comparison with another shoe.
