Description

 

Mongrel K9 Dealer Boots blend Aussie-built toughness with off-duty comfort. Premium full-grain leather, elastic-sided Chelsea fit and a cushioned OrthoTec® Lite footbed work with the AirZone® Comfort System for day-long support. Finished with an oil & fat-resistant TPU/PU sole for grip and durability—your go-anywhere boot for farm, yard and everyday wear.

Built by Mongrel Boots in Australia, the K9 is a non-safety dealer boot designed for everyday comfort without compromising durability. A streamlined Chelsea upper in premium leather sits over a supportive insole and shock-absorbing midsole, while the hard-wearing TPU/PU outsole resists oil and fat for reliable traction on farm and workshop surfaces. (Made in Australia, OrthoTec® Lite, AirZone®, TPU/PU sole)

Key Features

  • Premium full-grain leather: Softens with wear while retaining structure and protection.
  • OrthoTec® Lite footbed: Contoured, breathable cushioning for all-day comfort.
  • AirZone® Comfort System: Promotes airflow and moisture control inside the boot.
  • TPU/PU outsole: Oil & fat-resistant for grip and long service life on agricultural surfaces.
  • Elastic-sided Chelsea design: Quick on/off with a secure, unisex fit.
  • Non-safety toe: Ideal for off-site and general wear where a steel toe isn’t required.
  • Colours: Cloudy Grey, Claret, Heritage/Vintage Brown, Black.
  • Australian made: Crafted by Mongrel Boots, a family brand with decades of bootmaking heritage.

Typical Uses

  • Farm and yard work where comfort and flexibility matter
  • Workshop, warehousing and light trade use (non-safety)
  • Everyday wear—on the school run, in town or by the fire

Sizing & Fit

  • UK sizes: typically 3–14 available; selected half sizes (6.5–10.5) add width rather than length for extra room.
  • Fit tips: If between sizes, choose the half size for additional forefoot width; leather will relax slightly with wear.

Care & Maintenance

  1. Brush off dirt; wipe with a damp cloth and allow to dry naturally.
  2. Condition leather regularly to maintain suppleness and water resistance.
  3. Avoid prolonged chemical/oil saturation; rinse promptly if contaminated.
  4. Replace footbeds periodically to maintain cushioning and hygiene.

Why Choose Mongrel K9?

The K9 combines Chelsea-boot styling with serious comfort tech. Premium leather, a breathable, supportive insole and a grippy, workshop-ready outsole make it a dependable everyday boot that looks as good after hours as it feels on the job.

Feature set (OrthoTec® Lite, AirZone®, TPU/PU, premium leather), colourways and positioning are based on the manufacturer’s K9 range information and UK retailer specs.
