Argyle® Zip: Nitrile / Bump Cap / PR Midsole
Our 100% comfortable work boots are exclusively available from our network of authorised Steel Blue distributors
The Argyle® Zip Bump PR is a 150mm men’s lace-up ankle safety boot combining rugged protection with convenient industrial-grade side zip access. Designed for tradespeople who demand durability and comfort, this boot features a penetration-resistant midsole and a Moulded Bump Cap to protect against impact and abrasion in tough work environments.
Crafted from premium water-resistant Full Grain (Black) or Nubuck (Wheat) cowhide leather, the boot includes double nylon stitching, a padded collar and tongue, and non-corrosive lacing for lasting wear and comfort. The 200J Steel Toe Cap provides ultimate toe protection, while the Anti-static Nitrile Outsole resists abrasion and heat up to 300°C for superior durability.
Lined with soft, moisture-wicking Baltico® material, the Argyle® Zip Bump PR keeps feet cool and dry all day. A full-length polyurethane footbed and heavy-duty antibacterial insole support comfort and hygiene, while the directly moulded polyurethane midsole absorbs shock, easing fatigue.
Featuring Steel Blue’s patented Trisole® Comfort Technology, which uses PORON® energy-absorbing pads to cushion your feet, knees, hips, and lower back, this boot delivers all-day comfort on the job.
Available in Black Full Grain or Wheat Nubuck leather, the Argyle® Zip Bump PR is backed by our 30-Day 100% Comfort Guarantee.


Boot Technology
Leather
Boots made from high quality, long-lasting leather, including Nubuck, Full-Grain, TECtuff®, Suede and more.
Steel Toe Cap
Made from hardened steel for premium toe protection.
Nitrile Outsole
Superior resistance to abrasion and heat resistance to 300°C.
Slip & Oil Resistance
All Steel Blue footwear is designed to exceed the Slip resistance requirement in both the AS 2210.3 and EN ISO 20345. Our boots are rated as SRC which means that the footwear has been tested in laboratory conditions on both a ceramic tile floor with a Sodium Laureth Sulfate solution (SLS) and on a steel floor with Glycerine.
Anti-Static
Prevents the build-up of static electricity within your body by dissipating it through the sole.
Water Resistant
A treatment during the manufacturing process provides water resistance so that water is repelled from the surface.
Penetration Resistant
An extra tough steel midsole to prevent sharp objects getting through to your foot.
Bump Cap
A hardy, Polyurethane Bump that’s directly moulded as part of the midsole.
Lace Up
A classic fastening for snug, well-fitting work boots.


The Materials

Full Grain Leather & Nubuck Leather
Each Leather is specifically chosen to ensure the style of boot is fit for purpose and is ethically and environmentally sourced from members of the Leather Working Group (LWG).

Baltico® Lining
A soft, non-abrasive, hydrophobic material that wicks perspiration away from the foot, enabling the skin to remain cool and dry.

Ortho Rebound® Footbed
Our patented Ortho Rebound® Footbed is uniquely designed to reduce foot fatigue. Made from high quality Polyurethane, it always retains its shape and thickness to ensure support from heel to toe, is antifungal, and the high wicking material keeps your feet cool and dry.

Poron
Strategically placed high-tech Poron® pads are placed in the sole and under your foot’s peak stress areas. We included Poron® in our Trisole® Comfort Technology, which is now the benchmark for safety boots.
