The Thorogood GEN-Flex2 6″ Composite Safety Toe is the boot I point people to when they want American-made quality without the weight of steel. It sits at number five on my list of the best welding boots, and it earned that spot by doing the boring things well: clean stitching, a rebuildable sole, and a fit that respects wide feet.
I’ll say up front what I always say about composite toes. I prefer steel toes for heavy fabrication, where the shop drops real weight on real feet. Composite makes sense when you walk through metal detectors, spend your day on your feet, or just want a lighter boot. If that’s you, this review covers what the GEN-Flex2 does well and where it falls short.
Thorogood GEN-Flex2 6″ Composite Safety Toe Package Content & Technical Specifications
Package: one pair of boots. Thorogood ships these without extras, so budget for your own orthotics if the stock footbed doesn’t suit you (more on that below).

Pros
- Union-made in Wisconsin by Weinbrenner, a bootmaker since 1892
- Goodyear storm welt means the sole is stitched on and can be resoled
- Composite toe is roomy, lighter than steel, and wonu0026#8217;t trip metal detectors
- EH rated to CAN/CSA-Z195 for 18,000 volts of electric shock resistance
- Removable PU footbed with EVA Cushion Flex accepts custom orthotics
Cons
- Not waterproof, only water-resistant, and owners report inconsistent weather sealing
- Composite toe protects less than steel under serious impact in heavy fab
- Premium price for USA manufacturing
- 3.8/5 owner rating trails the other boots on my list
- Break-in takes about a week, and the storm welt can bite the ankle until it settles
Construction, Protection, and Fit on the Job
Leather and welt
The upper is brown tumbled oiled full-grain leather over a durable toe cap, and the lace-to-toe lacing pulls the leather down over your instep instead of leaving a gap at the flex point. Goodyear storm welt construction is the detail that matters most here. Instead of glue, the sole is stitched to the upper through a welt strip, so a cobbler can replace the outsole when it wears down.
That rebuildability is the whole argument for a Thorogood GEN-Flex2 at this price. The storm version of the welt also stitches the upper edge outward over the sole junction, which is why the boot resists water without a membrane.
Slag and sparks are the real test in a welding shop, and oiled full-grain leather shrugs off the small stuff. Deep spatter will mark any leather, so treat these like shop boots, not torch-proof armor. The same logic applies to the rest of your welding safety equipment: match the gear to the actual hazards on your floor.
Everything between the leather and your foot is non-metallic: the safety toe, the shank, and the hardware. Its composite toe meets ANSI/ASTM I75 and C75 impact and compression standards, so the protection is real, it just isn’t steel. There’s an electrical hazard rating to CAN/CSA-Z195 here too, tested for 18,000 volts of electric shock resistance, with an outsole that meets ASTM F3445 for slip resistance.
For welders, the honest framing is this: the EH rating is a bonus for anyone around live circuits, not a license to work hot. If you want the deeper checklist, my arc welding safety guide covers live-circuit precautions in detail.
The composite package
One naming note before you shop. Thorogood sells several boots under the GEN-Flex2 name, including an 8 inch waterproof tactical side zip boot with a heavy-duty YKK zipper. That side-zip design is a different boot built for security and uniform work, and the side zipper is the fastest way to tell them apart on a shelf. This review covers the 804-4445: the 6 inch lace-to-toe composite safety toe with the storm welt.
Inside, a removable single-density polyurethane footbed sits on an EVA Cushion Flex layer, and the compression-molded EVA midsole hides an Impact 300 gel insert in the heel. Under your arch, an engineered composite shank keeps the midfoot from collapsing on ladders, and the Anti-Roll Bar in the heel keeps the boot tracking straight on uneven ground.
Spacer mesh lining moves air better than a waterproof liner would, which matters if your shop runs hot. The multi-directional traction lugs under the rubber outsole are shaped for grip and resistance to oil and slick surfaces, so they hold going up a loading ramp as well as across a wet shop floor.
Underfoot, fit, and break-in
Thorogood builds these on a generous last: the heel holds, the instep is roomy, and the composite toe box runs wider than most steel-toe boots. Owners, including oilfield hands posting on the Amazon listing, generally report a true-to-size fit, so order your Brannock measurement. The removable footbed is the reason the boot takes orthotics well: pull the stock one out and your insert drops onto a flat, stable platform.
Comfort is where the money goes. At a listed 4.4 pounds for the pair, they’re not featherweight hikers, but the weight sits low in the dual-density rubber outsole instead of hanging on your ankle. One 340-pound oilfield reviewer reported 13 hours on concrete with no blisters and no tired feet on day one, which matches the design brief: EVA midsole, gel in the heel, shank doing the arch work. Break-in runs about a week.
The oiled leather starts stiff across the instep and the storm welt can bite the ankle until it settles, but the lace-to-toe pattern holds the boot snug without pressure points once it does. The 3M Scotchlite piping on the heel adds visibility if you walk a jobsite at dusk, and the oiled leather takes conditioner well, which is how a boot built for daily wear keeps its water resistance honest over the years.
Frequently Asked Questions [F.A.Q]
Is the Thorogood GEN-Flex2 good for welding?
Yes, with the right expectations. The oiled full-grain leather and storm welt handle sparks and spatter well for a leather boot, and the 6″ height keeps the collar below the crease at your ankle. It is not metatarsal protection: for heavy plate work overhead, a boot with a met guard belongs in the conversation.
Does the composite toe protect as well as steel?
It meets the same ANSI/ASTM I75 and C75 impact and compression standards, so the certification is equal. The difference is practical: steel shrugs off repeated heavy hits in a way composite doesn’t, which is why I run steel in heavy fab shops.
Is the GEN-Flex2 waterproof?
No. The storm welt makes it water-resistant, enough for wet grass and driveway puddles, but there’s no membrane. Owners who treat the leather report better weather sealing; owners who don’t report wet socks in steady rain.
Where are Thorogood GEN-Flex2 boots made?
In Wisconsin by the Weinbrenner Shoe Company, a union shop that has been making Thorogood boots since 1892. The GEN-Flex2 804-4445 is part of their USA-made line.
Conclusion
The GEN-Flex2 6″ Composite Safety Toe is the boot for the welder who wants USA-made construction, a resoleable storm welt, and a lighter foot than steel allows. It’s not the boot for heavy fabrication, and it’s honest about not being waterproof. Order your normal size, treat the leather, and it earns its premium price over years of resoles instead of replacements. That’s the whole case for it at number five on my best welding boots list, and it’s why I keep recommending it.
