Now, let’s dive into the details and find out how to choose the right work shoes!
1. Safety Shoes Standards (EN ISO 20345)
Key Safety Features
✔ Protective Toe Cap → Resistant to 200J impact & 15kN compression
✔ Slip Resistance (SRC, SRA, SRB) → Prevents falls on wet and slippery surfaces
✔ Puncture-Resistant Sole → Protects against nails and sharp objects
✔ Water & Chemical Resistance → Keeps feet dry and safe
✔ Electrical Protection (ESD & Antistatic) → Shields against static electricity
✔ Heat & Fire Resistance (HRO Standard) → Ensures protection in extreme heat conditions
2. Safety Shoe Soles: Impact on Safety and Comfort
The sole material is crucial for slip resistance, flexibility, and durability.
Types of Soles & Their Advantages
- PU (Polyurethane) → Lightweight, flexible, suitable for long-term use (S1, S2, S3)
- TPU (Thermoplastic Polyurethane) → Harder and more durable, high abrasion resistance, excellent slip resistance (S3, S5)
- E-TPU (Advanced TPU Foam) → Provides energy return, extra comfort, shock absorption (S1P, S3, ESD)
- Rubber (Nitrile) → Durable, heat-resistant up to 300°C (HRO), slip-resistant (S3, S4, S5)
- EVA (Ethylene Vinyl Acetate) → Lightweight, comfortable, shock-absorbing (S1, S1P)
- PVC (Polyvinyl Chloride) → Waterproof & chemical-resistant (S4, S5, S7S)
For dry environments → PU or E-TPU soles
For slippery and oily surfaces → TPU or rubber soles (SRC-certified)
For high-temperature environments → HRO heat-resistant rubber soles
For waterproof & chemical-protected areas → PVC or rubber soles
3. Safety Shoe Ankle Height: Comfort & Protection
Ankle height plays a role in mobility, support, and protection.
Types of Ankle Heights
✔ Low-Ankle Safety Shoes → More flexible, breathable (Ideal for indoor work)
✔ Mid-Ankle Safety Shoes → Balanced protection & mobility (Ideal for logistics & warehouses)
✔ High-Ankle Safety Boots → Maximum ankle support (Ideal for construction, roadwork, heavy industry)
For comfort & movement → Low or mid ankle shoes
For ankle support & injury prevention → High ankle boots
4. Safety Shoe Upper Material: Durability & Comfort
The upper material determines waterproofing, breathability, and durability.
Best Upper Materials
- Full-Grain Leather → Durable, waterproof, impact-resistant (S2, S3, S5)
- Nubuck Leather → Soft, flexible, lightly water-resistant (S1, S2, S3)
- Microfiber → Lightweight, chemical-resistant, easy to clean (S1P, S2, ESD)
- Mesh & Textile → Maximum breathability, lightweight (S1, S1P)
- Rubber & PVC → Fully waterproof & chemical-resistant (S4, S5, S7S)
For breathability → Mesh & microfiber uppers
For durability & protection → Leather uppers
For extreme waterproofing → Rubber & PVC uppers
5. Special Features: ESD and SRC-Certified Safety Shoes
⚡ ESD (Electrostatic Discharge) Protection
✔ Prevents electrostatic buildup in electronics & explosive environments
✔ ESD-certified shoes (EN 61340-5-1)
🦶 SRC (Slip Resistance Certification)
✔ Highest slip resistance level (SRA + SRB = SRC-certified shoes)
✔ Ideal for food industry, cleaning, warehouses, and construction
For electronics & sensitive work → ESD-certified shoes
For maximum slip prevention → SRC-certified soles
