Got these boots in April and have split in two places on the inside off one boot and the outside off the other not happy with the quality not even 12 months old
Was a nice and comfy pair of boots until the rear of the right foot was now started separating from the soul and you can see where the bottom of the soul is cannot I’ve been glued correctly?
Had a few pairs of these they last forever and great to wear straight out of box for 10 hours no need to break in
Only problem is trying t find brown ones (my prefered colour) impossible to find nowadays
Honestly the comfiest boots I have ever bought, no need to wear them in they are perfect from the second you put them on. It took me a while to get my head around the price but I was not disappointed. Look great, feel great, nice waterproofing and durable.
This is my second pair because they are wide fitting around the toe cap but they are very tight to get your foot in.
The first pair were great but these are just too tight.

I’m on my 2nd pair of spiro’s now, the first pair having lasted over two years on construction sites, one year of that doing 10 hour days, six days a week. If I had to pick a fault I’d say that they are a little on the heavy side but that’s probably the payoff for a pretty bulletproof boot. Waterproof and very comfortable. Recommended
Great pair of boots..completely waterproof and soooo comfortable 😁 good protection on the toe cap and not too heavy for steel caps. Would definitely buy these again 👌🏽
Very comfortable boots but a bit difficult to get your feet in and out of, worth the effort though as they didn’t make my feet hurt even when worn all day for the first time.
Boots look good and are super supportive. I suffer from planter fasciitis and these have given me some relief due to the instep being supportive under your feet.
Great boots! Very sturdy and fully waterproof..yeah they are a bit heavier than some other boots on the market, but they are super comfy and don’t make my feet ache at the end of the day..would highly recommend and would definitely buy these again 👌🏽
Great boots so far, only had a week, comfortable from the start, and great for my plantar fasciitis, I haven't even had to add any extra support, a great boot.
Only thing that would make them even better is as other people have said a pull on hoop on the back, but would buy these again as they are 😁
Always had the Spyro for years, sustained a broken heel, broken toes and a broken ankle due to a motorcycle accident a good few years back, struggled to find the right boot as I wear them all day at work, These boots are perfect, very comfortable after a week of bedding in, a bit warm in summer but you can't have all your eggs, by far the best fitting workbook I have ever had.
Best work boots I’ve ever worn, extremely comfortable straight out of the box and the quality give me confidence of there function and that they will last without having any issues with them.
Yes, selected Spiro Waterproof Safety Boot S3 Black include waterproof protection for wet-weather wear. Waterproof styles keep feet dry, whilst the leather upper adds durability. Because not every style is waterproof, check product details before ordering casual boots.
Are casual boots suitable for worksites?
Spiro Waterproof Safety Boot S3 Black are designed for everyday lifestyle wear, not work-site protection. They lack safety toe caps or site ratings. For protective footwear, our safety boots and safety trainers offer certified protection for work environments.
What do safety ratings SB, S1, and S3 mean?
Safety ratings show protection levels for safety boots. SB offers basic toe protection, S1 suits dry indoor work, and S3 suits wet conditions and high-impact sites. Because each rating serves different environments, choose based on your workplace hazards.
Are Spiro Waterproof Safety Boot S3 Black waterproof?
Many Spiro Waterproof Safety Boot S3 Black are waterproof, with sealed linings that prevent water ingress. Waterproof safety boots suit outdoor foul-weather work. Because some styles include insulation, these safety boots support comfort in cold and wet conditions.
What slip and heat protection do safety boots for men offer?
Many models include SRC slip resistance for contaminated surfaces and HRO heat resistance to 300°C. These safety boots suit work near hot equipment. Because safety boots combine grip with heat protection, they support safe movement on demanding sites.
What size should I choose in Spiro Waterproof Safety Boot S3 Black?
Spiro Waterproof Safety Boot S3 Black range from UK size 6, 7, 8, 9, 10, 11, 12, 13, supporting professional fits. Safety boots for men need slightly more room due to the protective toe. We recommend your usual size as we don't have measurements for feet in the size guide.
Which work environments suit safety boots for men?
Spiro Waterproof Safety Boot S3 Black suit construction, industrial, and manufacturing sites where impact and slip risks are common. Mens safety boots support operators and tradespeople during long shifts. Because every feature focuses on protection, safety boots perform in demanding work conditions.
