CARE TIPS
EVA shells are heat sensitive. They can warp if footwear is subjected to heat. Shoes and boots with EVA shells are light and comfortable, and should be stored properly to preserve their unique characteristics. Do not dry them in direct sunlight or under a hot light source. Do not dry them in the dryer or in front of a window, radiator, hair dryer, or other artificial heat source.
ESD footwear (Electrostatic Discharge footwear) is a type of specialized shoe designed to safely dissipate static electricity from the human body to the ground. This prevents harmful electrostatic discharges that can damage sensitive electronic equipment, ignite flammable substances, or disrupt precision operations.
It is a critical part of personal protective equipment (PPE) in ESD-safe environments, often used in conjunction with other grounding equipment such as wrist straps, anti-static mats, and ESD garments.
ESD footwear works by:
Creating a conductive path between the wearer’s body and the ground.
Containing a dissipative or conductive sole (typically made from PU, carbon, or rubber compounds).
Requiring direct contact with the skin through conductive socks or insoles to ensure effective discharge of static.
The footwear controls the flow of static charges and ensures it is released gradually and safely without generating harmful sparks.
| Parameter | Description |
|---|---|
| Electrical Resistance | Typically 10⁵ – 10⁹ ohms (ESD Class 1) |
| Standards | ANSI/ESD STM9.1, ASTM F2413, EN 61340-5-1, ISO 20345, CE EN ISO 20347 |
| Types | ESD shoes, ESD boots, ESD sandals, heel straps (for use with ESD floors) |
| Toe Protection | Options include soft toe, steel toe, or composite toe |
| Slip Resistance | Often conform to SRC, SRA, or SRB ratings |
| Industry | Usage Example |
|---|---|
| Electronics Manufacturing | Prevent component failure during PCB handling |
| Semiconductor & Microchip | Avoid latent defects in sensitive circuits |
| Cleanrooms | Ensure static control without particle emission |
| Aerospace/Defense | Protect avionics and radar systems from ESD |
| Automotive | During EV battery assembly or ECU testing |
| Pharmaceuticals | During drug development involving sensitive devices |
| Laboratories | While operating precision or optoelectronic tools |
ESD Safety Shoes
With or without toe protection.
Often used on factory floors and warehouse environments.
ESD Sneakers or Casual Work Shoes
Comfortable for long hours; suitable for office + production zones.
ESD Boots
Provide ankle support, often waterproof or chemical resistant.
ESD Slippers / Sandals
Used in cleanrooms or static-free testing zones.
ESD Heel or Toe Straps
Economical alternatives to full ESD shoes when paired with ESD flooring.
Outsoles: PU (Polyurethane) with carbon fiber, conductive rubber.
Upper: Leather, microfiber, or mesh.
Insole: Conductive or dissipative foam, often removable.
Stitching/Thread: Anti-static fiber integration.
| Type | Resistance Range | Use Case |
|---|---|---|
| Conductive | < 10⁵ ohms | Rarely used (too fast discharge) |
| Dissipative | 10⁵ – 10⁹ ohms | Ideal for ESD protection |
| Insulative | > 10¹¹ ohms | NOT suitable for ESD areas |
To ensure ongoing protection:
Test regularly using an ESD footwear tester or personnel grounding tester.
Clean soles with non-residue wipes or damp cloth (no wax or silicone).
Replace every 6–12 months or when resistance values fall out of range.
Store away from high heat and humidity.
Always wear with ESD flooring or grounding mats.
Use conductive socks or ESD-compatible insoles for skin contact.
Avoid using insulating socks like thick wool or synthetic materials.
Monitor regularly via wrist strap or foot tester stations.
Prevents product damage or failure due to ESD.
Ensures workplace safety and ESD compliance.
Enhances personal comfort and fatigue resistance (ergonomic design).
Offers optional toe and slip protection.
