In this buying guide you'll find expert advice from Indors on how to choose the best Work Boots and/or Safety Boots for your needs. There are dozens of different types of boots depending on the environment they'll be used in.
Let's look together at how they're classified and how to choose the right pair.
Main Types of Work Boots
Saying "work boots" might be reductive since there are many models, materials, shapes and safety grades that determine whether boots can be classified as safety footwear or not. That's why it's important to understand the main categories and their distinguishing features.
Thermal Boots
This type of boot is specifically designed for those working in cold environments, such as farmers or construction workers on outdoor sites during winter, as well as warehouse workers and operators in cold storage facilities.
These boots are typically made of leather, fur or high-thermal-insulation technical fabrics. However, being designed to keep feet warm, they're not always built for worker safety, so it's important to check their certification and safety level.
Steel-Toe Boots
Unlike the previous type, these boots are designed to protect feet in environments with falling object risks and puncture hazards. It's important to understand the protection type indicated on the label to determine which boots are suitable for your specific work environment.
PVC or Polyurethane Boots?
Both polyurethane and PVC are more durable than rubber but have important differences: Both are lighter than rubber, with polyurethane boots having the added advantage of being more flexible and resistant than PVC, thus lasting longer over time.
Protection Levels
SB (formerly standard S0): The basic protection level, least protective compared to others, featuring a 200 Joule steel toe cap for toe protection, meeting the main safety requirements of EN 345 standard.
S1 (formerly standard 01): Antistatic sole with heel energy absorption. Divided into: S1: No anti-puncture midsole S1P: Steel anti-puncture midsole S1PL: Metal Free anti-puncture midsole for 4.5mm nails (Large) S1PS: Metal Free anti-puncture midsole for 3mm nails (Small)
S2 (formerly standard 02): S1 + slight water resistance from leather (or similar) upper that resists water permeability for max. 60 minutes.
S3 (formerly standard 03): S2 + anti-puncture midsole. Divided into: S3: Steel anti-puncture midsole S3L: Metal Free anti-puncture midsole for 4.5mm nails (Large) S3S: Metal Free anti-puncture midsole for 3mm nails (Small)
S4: WRU water resistance.
S5: S4 + anti-puncture midsole. Divided into: S5: Steel anti-puncture midsole S5L: Metal Free anti-puncture midsole for 4.5mm nails (Large) S5S: Metal Free anti-puncture midsole for 3mm nails (Small)
S6: EXTRA water resistance (WR) Divided into: S6: No anti-puncture midsole S6P: Steel anti-puncture midsole S6L: Metal Free anti-puncture midsole for 4.5mm nails (Large) S6S: Metal Free anti-puncture midsole for 3mm nails (Small)
S7: S6 + anti-puncture midsole. Divided into: S7: Steel anti-puncture midsole S7L: Metal Free anti-puncture midsole for 4.5mm nails (Large) S7S: Metal Free anti-puncture midsole for 3mm nails (Small)
Slip Resistance Classes - EN 13287 (2012) standard:
SRA: Slip resistance on ceramic flooring with water and detergent SRB: Slip resistance on steel flooring with glycerin SRC: SRA + SRB
Risk Protection - 20345:2022 standard
P: Puncture resistant midsole E: Heel energy absorption WR: Water Resistance (improvement of WRU) WRU/WPA: Upper resistant to water penetration since 2023 AN: Ankle protection M: Metatarsal protection HRO: Sole resistant to heat contact at 300°C for 1 minute HI: Heat insulation up to 150°C CI: Cold insulation down to -17°C FO: Hydrocarbon resistant sole ESD: Protection against electrostatic discharge A: Electrostatic footwear C: Conductive footwear (electricity) CR: Cut resistance SRA: Slip resistance on ceramic flooring with water and detergent SRB: Slip resistance on steel flooring with glycerin SRC: Combination of SRA + SRB DGUV112-191: Orthopedic footbed adaptation SC: Toe abrasion resistance LG: Sole with heel detached from footbed for ladder rung grip
The last essential feature we want to highlight in safety footwear is its resistance to electrostatic discharge, indicated by the ESD (ElectroStatic Discharge) marking, which refers to static electricity discharge between bodies that can be hazardous in work environments because, even if weak, it can ignite fires when flammable materials are present. These boots are recommended in environments working with microchips, production of sensitive electrical components, painting, laboratories, medical fields, and when working with flammable liquids and gases.
