MR Yellow PU Boots

MR PU Flame-Retardant Protective Rain Boots (Yellow)

With Safety Toe & Anti-Puncture Midsole

Engineered for high-risk environments where fire hazards and wet conditions coexist, these black PU flame-retardant rain boots deliver reliable protection without compromising comfort or mobility.

Multi-Layer Safety Protection

Safety Toe Cap – Equipped with a steel or composite safety toe, these boots provide impact resistance up to 200 joules and compression resistance up to 15,000 newtons, effectively protecting feet against falling debris, collapsing structures, and heavy equipment encountered in fireground operations.

Anti-Puncture Midsole – The built-in steel or Kevlar® midsole delivers penetration resistance up to 1,100 newtons, shielding the foot from nails, glass shards, rebar, and other sharp objects scattered across post-fire and rescue sites—a critical feature when walking through debris-strewn environments.

Flame-Retardant Construction – The PU upper is specially formulated with flame-resistant properties, providing a heat barrier that helps reduce burn risk in high-temperature environments. The material is self-extinguishing and resists molten metal splashes, making it suitable for proximity to fire and extreme heat.
