Puma Safety Crosstwist Black Mid SB Safety Boots

Puma Safety Crosstwist Black Mid SB Safety Boots

The Crosstwist Black Mid is an SB-rated boot whose distinguishing point is its Electrical Hazard (EH) outsole. The supplier states that it gives secondary protection against incidental contact with live electrical circuits, in line with the US norm ASTM F2413-24. Toe and underfoot protection are non-metallic, under a leather and textile upper.

Key features

• EH outsole: Rated EH under ASTM F2413-24.
• No metal in the protection: A lightweight fibreglass toe cap is paired with flexible, non-metallic FAP perforation protection.
• Sprayed-on guards: The toe cap and heel have sprayed-on protection.
• Torsion control: A TPU element supports the natural movement of the foot and adds stability.
• Cushioning: An evercushion Custom Fit Mid footbed, lightweight midsole and idCell heel element absorb shock.
• Rubber outsole: Slip resistant and heat resistant up to 300°C, with a rotation point to reduce walking fatigue.

Typical uses

Recommended by the supplier for data centre work. The EH property is described as secondary protection only, so the boot should be selected in line with the site's risk assessment.
