Base Yellowstone S3S ESD Low Safety Work Shoes B0666B
Looking for reliable work shoes that won't compromise on protection or comfort? The Base Yellowstone S3S ESD Low Safety Work Shoes deliver serious performance for demanding environments. Built with a 200 joule non-metallic protective nose, these low-cut safety shoes shield against impact whilst remaining entirely metal-free, making them ideal for electronics-sensitive workplaces. The penetration-resistant sole keeps sharp objects at bay, whilst the energy-absorbing heel reduces fatigue during extended shifts. With antistatic properties and ESD protection, they safeguard both you and sensitive equipment. The oil-resistant running sole handles hydrocarbon exposure confidently, and the anti-slip grip works across ceramic and steel surfaces. Available in narrower fits for both men and women, these sporty work shoes combine protective features with everyday wearability.
Key Features
- 200 joule non-metallic protective nose for impact defence
- Penetration-resistant sole shields against sharp hazards
- Entirely metal-free construction with ESD protection
- Energy-absorbing heel reduces fatigue on long shifts

Recommendations from our Unishore Expert
These work shoes excel in environments where electronics protection matters. The metal-free design eliminates concerns about conductive materials, whilst the ESD properties safeguard sensitive equipment during handling. The breathable upper construction keeps feet fresh throughout the day, and the orthopaedic footbed provides genuine arch support without compromising the sporty profile. Choose these if you need serious protection that doesn't feel clunky, particularly in industrial settings, manufacturing facilities, or electronics assembly areas where static control is non-negotiable.

Step 1 : Stand upright on a hard surface with your heel against the wall and a blank sheet of paper taped to the floor

Step 2 : Have someone mark the longest part of the foot (Heel to toe) with a pen or pencil, repeat this for the same foot because sizes may differ per foot.

Step 3 : Use a ruler to measure the heel-to-toe length with the longest toe perpendicular to the wall
