A lower shaft with a defined heel
The matching Thorogood 804-4375 uses MAXWear 90 rather than MAXWear Wedge. The distinction matters for shoppers who need a pronounced heel profile or prefer how that shape interacts with their approved work surfaces. A broad slip-resistant label cannot tell you whether a boot meets a specific employer’s heel requirement.
At the upper, the 6-inch format gives less lower-leg coverage than the 8-inch Crazy Horse boot. That is a straightforward design choice: compare where the collar sits and how it works with your trousers rather than assuming additional shaft height is always an upgrade.
Keep the American Heritage options straight
Thorogood sells multiple safety and non-safety moc-toe configurations. For a replacement purchase, the style number and steel-toe designation are more reliable identifiers than the leather color. Crazy Horse is not a waterproof certification, and a moc seam does not identify what material is inside the safety cap.
The closest alternatives are the 8-inch MAXWear 90 if you need more shaft coverage and the 6-inch wedge if your priority is a continuous outsole. The waterproof 1957 line adds another meaningful variable, so compare it separately rather than treating it as a color upgrade. This listing specifies D width; the separate 11-2E listing is a different size/width selection of the heeled format. There is no basis to describe that larger, wider option as having a tougher sole or higher protection rating.
