A color listing with a model-code question
The title identifies a moc steel-toe work boot, waterproofing and a polyurethane cushion insole. Carhartt publishes those features for its waterproof moc wedge family, but this marketplace title does not include a style number. A matching appearance is not sufficient to establish an exact outsole or manufacturing revision.
Ask the seller for the tongue label if the sole shape, current slip-test standard or specific electrical-hazard marking is important to your purchase. This avoids attributing specifications from a newer Carhartt page to older stock sold under a familiar name.
How to judge the 10.5 medium
The medium width and the steel-cap shape are the fitting questions that matter. Lace the boot with your usual work socks, then check how the foot sits during a forward step. A comfortable upper cannot compensate for the cap pressing on the side or top of your toes.
Dark brown is an appearance choice, not a verified material upgrade over soft tan. If both listings resolve to the same style family and fit, compare the seller’s selected size, condition and return terms rather than treating them as different performance tiers.
Understand the EH wording
Electrical-hazard footwear provides secondary protection under specified conditions; it does not authorize work on energized equipment. Waterproofing and EH also describe different properties. Follow the employer’s electrical-safety procedure and check the supplied boot markings instead of reading either claim as protection in every wet environment.
