Model identity before the size conversion
The N1393 model number is the strongest part of this listing. SureWerx’s manufacturer selection places it in women’s footwear and lists steel toe and SD10. The marketplace title omits gender, so treating the number 8 as a men’s size would change the intended selection. Match the women’s model and retailer size chart before ordering.
This is also a case where a general industrial category can be less informative than the exact code. A retailer may group the item under work shoes or construction footwear, but that category does not establish boot height, waterproofing, or additional protective features.
What to do with the SD10 designation
Static-dissipative footwear is selected for a particular workplace electrical-control requirement. Do not interpret SD10 as an electrical-shock protection claim or assume it is interchangeable with an EH shoe. Give the exact N1393 documentation to the person responsible for the footwear policy if the requirement is unclear.
A replacement insole can change the intended footwear configuration. Ask the maker about compatible replacements rather than installing a thick comfort insert solely because it fits physically. You also need sufficient space beneath the rigid toe cap after any approved change.
Compare within women’s work footwear
Nautilus Westside N1435 is another identified women’s steel-toe SD option, with a different casual presentation. Its size-7 listing is not a direct replacement for this size-8 selection. Compare model fit and required electrical properties first, then select the appropriate size within the chosen model. There is no evidence here that one is inherently more comfortable or better for every foot shape.
