Rigger boots are pull-on safety boots. No laces, no buckles. Just slip them on and get to work. They're the most popular work boot on UK construction sites — and one of the most misunderstood. This guide covers what a rigger boot is, how the EN ISO 20345 ratings work, and how to pick the right one for your job. For a broader look at work boot options including wellingtons, read our Complete Guide to Wellington Boots for Work.
What is a rigger boot?
A rigger boot is a mid-calf pull-on safety boot. It has two pull loops at the top, a leather upper, and a fleece or faux-fur lining. No laces, no zips, no buckles. You pull it on. You pull it off. That's the whole idea.
The name comes from the North Sea oil rigs. Workers needed boots that came off fast. If someone went overboard, laces were a death trap. The pull-on design let them kick the boots off in the water. That history shaped the boot we use today.
Modern rigger boots follow the same basic shape. The key features are:
- Pull loops at the top — easy on and off
- Fleece or faux-fur lining for warmth
- Leather upper — usually full-grain or crazy horse leather
- Mid-calf shaft height
- Steel or composite toe cap
- Slip-resistant outsole
Some models add waterproof membranes, puncture-resistant midsoles, or heat-resistant outsoles. The core shape stays the same.
Who needs rigger boots?
Rigger boots suit jobs where you need safety footwear and value speed and warmth. Here's who reaches for them most.
Construction and groundworks
Site workers love rigger boots. They're easy off at the welfare cabin. They keep feet warm on cold mornings. For groundworkers on firm or hard-standing surfaces, they're a practical daily choice.
Utilities and highways
Gas, water, and telecoms engineers work in and out of vehicles all day. A pull-on boot saves time at every stop. Road workers on tarmac need an HRO (heat-resistant outsole) — more on that below.
Agriculture and rural trades
Farmers and rural workers deal with cold, mud, and wet ground. A warm, waterproof S3 rigger handles most farm tasks well. It sits between a welly and a lace-up safety boot.
Warehousing and maintenance
On hard floors, rigger boots are comfortable for long shifts. They won't suit every warehouse — some sites require safety trainers. But many workers prefer the warmth and comfort they give.
Rigger boots don't suit every site or job. The lace-up comparison section below explains when to choose differently.
EN ISO 20345 ratings decoded
Every safety boot sold in the UK must meet EN ISO 20345. This standard sets the minimum protection a boot must give. All certified boots have a 200-joule steel toe cap. That's a 20 kg weight dropped from 1 metre onto your toes. The compression test is 15,000 newtons — roughly 1.5 tonnes pressing down. Figures confirmed by uvex-safety.co.uk and ejendals.com in their technical breakdowns of EN ISO 20345.
After that base, the rating letters tell you what extra protection you get. Here's what each one means in plain terms:
- SB — Steel toe cap only. Nothing else. The bare minimum. Fine for low-risk indoor use.
- S1 — Toe cap, anti-static sole, and energy-absorbing heel. Good for dry indoor work.
- S1P — Everything in S1, plus a nail-proof midsole. A nail can't poke up through the sole. Good for construction sites with nails and sharp debris.
- S2 — S1 protection plus a water-resistant upper. Handles splashes, not deep puddles.
- S3 — The most popular on UK sites. S1P protection plus a water-resistant upper and a cleated outsole. Good grip in mud and wet. The go-to for most outdoor trades.
- S4 — Full polymer or rubber boot. Waterproof all the way through. No leather.
- S5 — S4 with a nail-proof midsole. The waterproof choice for very wet or chemical-risk jobs.
- S6 and S7 — New in the EN ISO 20345:2022 update. S7 is essentially S3 plus full boot waterproofing. Useful when you need both a cleated outsole and zero water penetration.
For most construction and groundworks, S3 is the minimum worth buying. S1P works on drier, hard-standing sites.
One thing to note: the standard was updated in 2022. Some boots on sale still carry EN ISO 20345:2011 certification. Both are legal — manufacturers had until November 2024 to re-certify under the new version, and certified 2011 products can sell until November 2029. Neither version is wrong. Just check the label matches your site's requirements.
What the extra markings mean
Beyond the S-rating, boots carry extra letter codes. Each one means something specific. Here are the ones that matter most for rigger boot buyers.
- HRO — Heat-resistant outsole. The sole handles contact with surfaces up to 300°C. You need this for roadworks, tarmac laying, and jobs near hot materials. Without HRO, the sole can soften and fail on hot ground.
- CI — Cold insulation. The sole is insulated against cold surfaces. Useful for cold-store work and winter groundworks on frozen ground.
- LG — Ladder grip. New in the 2022 standard. The sole is shaped and stiffened to grip a ladder rung safely. Scaffolders and steelworkers should look for this mark.
- SR — Slip resistant on oily surfaces. The 2022 standard replaced the old SRC marking. SR means the boot passed a tougher oily-surface test on a ceramic tile. Useful for plant operators and anyone near machinery fluids.
- P / PL / PS — Nail protection types. P uses a steel insert. PL and PS use non-metal inserts tested with different nail sizes. All three stop a nail through the midsole. PL and PS are metal-free — important for airport and rail sites.
- WR — Full water resistance of the whole boot. Under the 2022 standard this means zero water gets in. Stricter than the 2011 version, which allowed a small amount of penetration.
- WRU — Water-resistant upper only. The leather resists water, but seams may let water in over time. Not the same as WR.
Most rigger boots on UK sites carry an S3 HRO or S3L HRO rating. That covers construction, highways, and groundworks. The HSE's slip-resistant footwear guidance confirms that sole compound and tread pattern both affect real-world performance — always trial footwear in your environment where you can.
Are rigger boots waterproof?
Not all of them. The rating tells you exactly what you have.
- S1 and S1P — No waterproofing. Fine on dry sites. Not for wet ground.
- S2 and S3 — Water-resistant upper. Handles rain and wet mud. Won't cope with standing water deep enough to top the boot.
- S5, S7, and WR-rated boots — Fully waterproof construction. The whole boot keeps water out.
For outdoor work in the UK, S3 is the sensible minimum. Most working days involve some wet ground. A WRU-rated leather rigger handles most conditions. If you're wading through drainage trenches every day, look at S5 or a safety welly instead. Our Wet Weather Work Gear guide covers foot protection for tougher conditions.
Rigger boots vs lace-up safety boots
Both can be fully EN ISO 20345 certified. The difference is fit and ankle support — and that matters for some jobs.
| Choose a rigger boot when… | Choose a lace-up when… |
|---|---|
| You're on firm, flat, or hard-standing ground | You're on loose, uneven, or unstable ground |
| You get in and out of a vehicle often | You need a close, adjustable fit around the ankle |
| Warmth matters — cold mornings, outdoor winter work | Your site rules require lace-up boots |
| You're on a hard-standing yard or warehouse floor | You're on slopes, scaffolding, or rough terrain |
| Speed on and off matters during your day | Ankle stability is a priority for your task |
Honest answer: a rigger gives less ankle support than a laced boot. Some companies have found their workers are more likely to suffer a twisted or sprained ankle in a rigger boot on uneven ground — because the looser fit makes it harder to stop the foot twisting sideways. That's not a reason to avoid rigger boots. It's a reason to match the boot to the surface.
On firm ground, riggers are a sound daily choice. On loose rubble, slopes, or rough terrain, a lace-up is the safer call. See our guide to Steel Toe vs Composite Toe Safety Boots for more on construction footwear choices.
Are rigger boots banned on construction sites?
No. There is no national ban. The HSE has not banned rigger boots. They are legal safety footwear when certified to EN ISO 20345.
Some principal contractors have banned them on their own sites. That's their right. They set access rules above the legal minimum. The reason is nearly always ankle support — on sites with a lot of uneven ground or loose rubble, some contractors want everyone in lace-up boots.
Under the PPE at Work Regulations 1992, employers must provide PPE that's right for the risk. The law specifies the standard, not the style. A rigger boot rated to EN ISO 20345 is legally compliant PPE.
The practical advice: always check site rules before ordering for a team. If a principal contractor mandates lace-ups, you need lace-ups. If there's no such rule, a certified rigger boot is a perfectly legal choice.
Our picks: rigger boots worth buying
Here are options from our range, chosen for different jobs and buyers. All are EN ISO 20345 certified.

Frequently asked questions
Are rigger boots banned on construction sites?
No. There is no national ban in the UK. The HSE has not banned rigger boots. Some individual principal contractors ban them on their own sites due to ankle support concerns on uneven ground. Check your site's PPE rules before ordering. A rigger boot rated to EN ISO 20345 is fully legal safety footwear under the PPE at Work Regulations 1992.
Are rigger boots waterproof?
Not all of them. S1 and S1P rated boots have no waterproofing. S2 and S3 rated boots have a water-resistant upper — good for rain and wet mud, not deep standing water. For full waterproofing of the entire boot, look for S5, S7, or the WR marking. For most UK outdoor work, S3 is the minimum worth buying.
What is the difference between S1P and S3 rigger boots?
Both have a 200-joule toe cap and a nail-proof midsole. S3 adds a water-resistant upper and a cleated outsole for better grip in mud and wet conditions. S1P suits drier, indoor, or hard-standing environments. For outdoor construction or groundworks in the UK, S3 is the stronger choice.
Do I need a risk assessment before issuing rigger boots to my team?
Yes. Under the PPE at Work Regulations 1992, all PPE must be chosen based on a suitable risk assessment of the workplace and the tasks involved. The assessment should cover ground conditions, hazards present, and any site-specific rules set by the principal contractor. The law requires the right PPE for the risk — not just any certified boot.
What is the best rigger boot for construction work in the UK?
For most UK construction and groundworks, an S3 rated leather rigger boot is the right starting point. If workers are on tarmac, roadworks, or near hot surfaces, look for an S3 HRO option — the heat-resistant outsole matters there. Always check your site's PPE requirements before ordering for a team.
