BAD OXYGEN™ ULTRA-LIGHTWEIGHT ZIP SIDE SAFETY WORK BOOTS

THE WORLD'S MOST LIGHTWEIGHT WORK BOOTS

Weighing in 33% lighter than the average industry work boot, this ultra-lightweight sneaker boot feels like a running shoe delivers heavy-duty site protection. Featuring a highly breathable mesh base with athletic structural "caged" overlays, it eliminates dead weight and delivers maximum airflow, giving your feet the oxygen they need to float through a 12-hour shift without fatigue.

• Ultra-Lightweight: Clocking in at just 550 grams per boot (Size 8), these are a massive 33% lighter than traditional work boots, drastically reducing leg fatigue.

• Maximum Breathability: High-airflow mesh panels let your feet breathe, actively cooling you down during blistering summer days.

• Heavy-Duty Side Zip & Strap: Forget lacing up every morning. We’ve integrated a premium medial side zipper with a secure velcro top-strap for lightning-fast on and off.

• Premium Anti-Fatigue Insole: Each pair comes pre-loaded with a massively thick, shock-absorbing support innersole to actively reduce knee and lower back pain.

• Engineered Safety Toe Cap: Maximum certified protection against site hazards, without the heavy, clunky profile.

• Shock-Absorbing Midsole: Lightweight EVA foam cushioning that takes the impact of hard concrete floors so your joints don't have to.

• Durable Outsole with Flex Grooves: Enhanced traction and flexibility designed to move naturally with your foot.

• Covered by Warranty: Quality assurance for long-lasting durability on the toughest Aussie sites.

2. Product Details

While average work boots tip the scales at over 800 grams, this featherweight design clocks in at a remarkably light 550g (Size 8). By replacing heavy, traditional materials with an athletic, track-inspired "caged" mesh upper, we have created the world's most lightweight work boots.

This massive 33% reduction in weight is the ultimate solution for workers suffering from foot, knee, or back fatigue. The upper features highly durable synthetic overlays combined with a moisture-wicking, breathable mesh base. This creates a locked-in, secure fit that drastically reduces drag while supplying a constant flow of cooling oxygen to the foot in the harsh Australian summer heat.

Underfoot, an ultra-lightweight foam midsole is paired with our premium anti-fatigue gel-support innersole. Engineered specifically for tradies working long hours on unforgiving concrete surfaces, it actively absorbs impact with every step. Complete with an engineered steel toe cap, a heavy-duty side-access zipper, and a slip-resistant outsole, you get uncompromising safety at a fraction of the weight. Designed and registered in Melbourne, Australia.
