Puma Safety Krypton Blue Mid S3 ESD SRC Safety Boots
Experience lightweight protection, flexibility and lasting workplace comfort with the Puma Safety Krypton Blue Mid S3 ESD SRC Safety Boots. Part of the innovative Puma Safety Technics Line, these metal-free safety boots combine athletic-inspired movement with dependable S3 protection for demanding industrial and trade environments.
The black and blue upper is manufactured from durable oiled nubuck leather, providing a premium appearance with improved resistance to moisture and everyday wear. A mid-cut design offers additional coverage and support around the ankle without the excessive weight or stiffness associated with traditional safety boots.
Lightweight, metal-free protection
The Krypton Blue Mid features a strong yet lightweight fibreglass safety toe cap, helping protect the toes against workplace impacts and compression. Its flexible, metal-free FAP® penetration-resistant midsole provides underfoot protection against sharp objects while allowing the boot to move naturally with the foot.
Because its main protective components contain no metal, the Krypton Blue Mid remains flexible and comfortable while also being suitable for working environments where metal-free safety footwear is preferred.
Flexible naturalFLEXMOTION® sole
At the heart of these Puma safety boots is the naturalFLEXMOTION® sole architecture, created to bring the feel of natural running technology to professional safety footwear. The flexible double-density PU sole supports natural foot movement while providing excellent cushioning and stability.
Its specially designed wafer tread delivers reliable grip, particularly on smooth industrial floors. The tread is also easy to clean and provides secure contact when working on ladders.
An integrated iCELL cushioning element uses a durable honeycomb structure to absorb impact, improve stability and support controlled movement throughout the working day.
All-day comfort and moisture management
The anatomically shaped evercushion® BA footbed uses layers of cushioning foam to support the heel, forefoot and longitudinal arch. This helps distribute pressure, maintain a natural foot position and reduce fatigue during prolonged periods of standing or walking.
A moisture-regulating, open-cell construction helps move perspiration away from the foot. Combined with the breathable BreathActive functional lining, it supports a fresher and more comfortable environment inside the boot during long shifts.
ESD protection for sensitive workplaces
These ESD safety boots are designed to dissipate electrostatic charge in a controlled manner. This makes them suitable for workplaces containing sensitive electronic components, equipment or materials that could be damaged by electrostatic discharge.
The combination of S3 protection, ESD performance and SRC slip resistance makes the Krypton Blue Mid a versatile option for engineering, manufacturing, warehousing, assembly and logistics.
