The Mercury Stone S7L Waterproof Safety Boots deliver dependable protection and comfort for trades working outdoors in all conditions. A fully non-metallic build keeps weight down while the composite toe cap and composite penetration-resistant midsole provide serious safety without the bulk of steel.
A waterproof, breathable membrane teams with Thinsulate™ insulation to keep feet dry and warm. Underfoot, the phylon/rubber outsole offers confident grip, is HRO heat resistant to 300°C, FO oil/fuel resistant, and certified to the highest SR slip rating. A scuff-cap reinforces the toe for long-lasting durability.
Versatile and hard-wearing, Mercury Stone is ideal for construction, utilities, landscaping, rail, and general outdoor trades where waterproof performance, non-metallic safety, and all-day comfort are non-negotiable.
