The STC Shire, Keep, and Trump are waterproof, vegan safety boots with a wide fit, but they are built for different jobs. The Shire uses a metal-free composite safety system and a Vibram outsole. The Keep and Trump use steel protection, 200-gram Thinsulate insulation, and Chemtech microfiber uppers. The deciding factors are the work environment, required safety system, and preferred shaft height.
Choose the Shire for mixed construction sites, metal-free requirements, and a more specialized Vibram outsole. Choose the Keep for cold, wet, or chemical-exposure work where an 8-inch shaft and 200-gram insulation are useful. Choose the Trump when the Keep's core materials and steel protection are preferred in a shorter 6-inch boot. There is no universal winner; the right choice depends on the hazard assessment and the workday.

The Main Differences That Matter on Site
Safety toe and puncture protection
The Shire is the only metal-free model in this comparison. STC pairs a composite toe with composite puncture protection and polymer hardware. That makes it the logical starting point when the site limits metal in footwear or when a non-metallic safety system is preferred.
The Keep and Trump use steel toes and steel puncture-resistant plates. Steel is not automatically better than composite, or the reverse. The required certification and the complete boot matter more than the toe material by itself. STC identifies all three models with CSA Grade 1 toe and puncture protection plus electric shock resistance.

Waterproof systems and upper materials
The Shire combines tear-resistant ballistic nylon and Chemtech material with sealed seams and a waterproof, breathable Sympatex membrane. This construction is useful where workers move between rough surfaces, mud, and changing weather.
The Keep and Trump use waterproof Chemtech microfiber with STC's H2O Seal seam system. STC markets Chemtech for resistance to water and several substances found in food-processing, agricultural and industrial settings. That is a manufacturer claim, not permission to treat the boots as protection against every chemical. The site's chemical assessment and the product-care guidance still apply.
Height, insulation and outsole
The Shire and Keep are both 8-inch boots. The Trump is 6 inches, giving it a lower collar and less lower-leg coverage. Keep and Trump both list 200-gram Thinsulate insulation. STC does not publish an insulation weight for the Shire, so it should not be presented as equivalent in warmth based on appearance alone.
Underfoot, the Shire uses a dual-density Vibram TC4+ outsole with natural rubber and a lightweight polyurethane core. The Keep and Trump use lightweight, oil-resistant polyurethane outsoles.
All three have a 90-degree heel and scuff protection, but outsole choice should still be matched to the surface and the site's slip-control requirements.

STC Shire Review: Metal-Free Protection for Mixed Construction
The Shire is the most differentiated boot of the three. Its composite safety toe and puncture protection, polymer eyelets, waterproof Sympatex membrane and Vibram TC4+ outsole create a strong package for general construction, utilities and mixed indoor-outdoor work. The ballistic nylon upper also sets it apart from the microfiber construction used on the other two models.
Why choose it: It is the clearest option when a metal-free boot is required, and its outsole and 8-inch height suit varied jobsite conditions.
What to consider: STC does not list a gram weight for insulation. Do not assume it will match the Keep or Trump in colder, more stationary work. Composite construction also does not prove that the complete boot is the lightest; STC does not publish comparable boot weights for these models.
STC Keep Review: An 8-Inch Boot for Cold, Wet Work
The Keep combines an 8-inch Chemtech microfiber upper, H2O Seal waterproof construction, 200-gram Thinsulate, and steel toe and plate protection. STC specifically positions the model for environments such as food processing and cold storage, where moisture, cooler conditions, and frequent cleanup can shape the footwear decision.
Why choose it: It offers more shaft coverage than the Trump while keeping the same key insulation and Chemtech material concept. It is the stronger of the two when the work environment favors an 8-inch boot.
What to consider: The Keep is not metal-free. Its metal eyelets and steel safety system can also be a mismatch where site rules call for non-metallic footwear. The 8-inch shaft provides more coverage, but workers who prioritize a lower collar may prefer the Trump.
STC Trump Review: The Lower-Cut Chemtech Option
The Trump carries over the Keep's central formula in a 6-inch profile: waterproof Chemtech microfiber, H2O Seal seams, 200-gram Thinsulate, a steel safety toe, and steel puncture protection. The shorter shaft is the practical difference. It gives workers a lower collar while retaining the same published insulation weight and safety materials.
Why choose it: It fits warehouse, maintenance, and trade work where a lower boot is preferred, and an 8-inch shaft is not required by the task or site policy.
What to consider: It provides two inches less shaft coverage than the Shire and Keep. That can matter in deeper mud, splash, or debris. Like the Keep, it is not metal-free.
Which STC Boot Fits Your Jobsite?
Best STC boot for general construction: Shire
For a typical mixed construction site, the Shire is the most balanced starting point. The metal-free safety system, 8-inch height, 90-degree heel, scuff bumper, waterproof membrane and Vibram TC4+ outsole cover a broad range of common demands. This recommendation changes if the employer specifically requires steel protection or if insulated cold-storage work is the priority.
Best for cold storage, food processing or wet industrial work: Keep
The Keep is the better fit when an 8-inch waterproof Chemtech boot and 200-gram insulation align with the environment. Its steel safety system also suits sites that specify steel. Confirm compatibility with any chemical exposure rather than relying on the broad material description alone.
Best for a shorter work boot: Trump
The Trump is the practical choice when the job calls for waterproofing, 200-gram insulation and steel protection without an 8-inch shaft. It is not a lighter boot by published weight, because STC does not provide a comparable figure. Its advantage is the lower 6-inch profile.
Fit, Sizing and Current Availability
STC lists all three boots as wide fit. STC's size guide notes that centimetre measurements refer to foot length, not the outside length of the boot. Fit should be confirmed with the socks and any orthotics normally worn on the job. A safety boot that is too tight can reduce comfort, while excessive movement can create friction and instability.

A Note on CSA and Electric Shock Resistance
STC explains that the CSA Grade 1 green triangle represents 125-joule toe protection and puncture resistance of at least 1,200 newtons. Its orange electric-shock-resistance marking is tested at 18,000 volts with leakage not exceeding 1 milliampere. STC also warns that this protection deteriorates rapidly in wet environments and with wear. The label is not a substitute for electrical isolation procedures or job-specific PPE.
Final Recommendation
Choose the STC Shire 8-inch boot for the strongest general-construction option in this group when metal-free protection and a Vibram outsole fit the site. Choose the STC Keep 8-inch boot for colder, wet work that benefits from an 8-inch Chemtech upper and 200-gram insulation. Choose the STC Trump 6-inch boot when the same basic insulated steel-toe concept is preferred in a lower profile.
Compare all available models in the STC Footwear collection and confirm the employer's hazard assessment, required certification, fit, and current size availability before ordering.
