Endurance S7S Barefoot Safety Boots

The Endurance S7S brings the highest classification in the safety footwear standard to a boot built for barefoot movement. Waterproof, penetration resistant and flat from heel to toe, it is made for professionals who work long days on wet ground and need serious protection without giving up comfort, mobility or a natural gait.

Key Features

Wide Toe Box
Allows natural toe splay and improved balance.

Zero Drop Sole
Flat from heel to toe to encourage natural posture and movement.

Waterproof Construction
Whole-boot water resistance, tested on the complete boot and not just the upper.

Composite Toe Cap
200 J impact and 15 kN compression resistance, without the weight of steel.

Penetration Resistant Insert
Flexible non-metallic underfoot protection, tested with the 3.0 mm nail.

Energy Absorbing Heel
Absorbs shock at the heel without raising it. Patent pending, GB2616919.3.

Slip Resistant Outsole
Cleated grip tested on wet and oily surfaces.

Fuel & Oil Resistant Sole
Built for industrial use.

Antistatic and Static Dissipative
Safely disperses static charge underfoot.

Vegan Microfibre Upper
Durable, easy to clean and free from animal-derived materials.

Certified to EN ISO 20345:2022+A1:2024 S7S FO SR, Class I, and tested to ASTM F2413-24 and ASTM F3445-24.

Comfort Benefits
Unlike conventional narrow safety boots with a raised heel, the Endurance S7S is built to let the foot move as it was designed to, shift after shift.

We make footwear that protects your feet without fighting against them.

Born from traditional shoemaking and shaped by years of craftsmanship, Gaucho Ninja creates barefoot footwear that balances health, function, and timeless design.

Our Philosophy

Natural movement matters. Your feet were designed to move, spread, flex, and support you. We build shoes that respect that design.

Designed in the UK

Each model is developed with a focus on performance, comfort, and honest craftsmanship.

Made with Care

We work with specialist manufacturing partners to produce footwear to demanding standards.

Independent Brand

Gaucho Ninja is an independent company built through craftsmanship, innovation, and a passion for better footwear.

Use

• Wear with suitable work socks. Do not wear without socks.
• Ensure correct fit and lace securely to the top hook before use.
• Always wear with the insock in place. The footwear was tested with it fitted.
• Use only for occupational environments requiring certified protective footwear.
• Always select the correct size to maintain proper toe cap positioning.
• If you are new to zero-drop footwear, build up wearing time gradually.

Restrictions of use

• Water resistant for walking in wet conditions. Not designed for immersion or prolonged standing in water above the sole.
• No metatarsal, ankle, chainsaw, chemical, or electrical arc protection.
• No insulation against cold, extreme heat, hot contact surfaces, or molten metal splash.
• Antistatic footwear is not electrically insulating. Not suitable for work on live electrical installations.
• Not metal free. The lacing hooks and eyelets are metal.
• Do not modify, drill, cut, or alter the footwear. This may void certification.

Cleaning

• Remove loose dirt with a soft brush.
• Clean with a damp cloth and mild soap if required.
• Do not use solvents, bleach, caustic or aggressive chemicals.

Drying

• Remove the insock and air dry naturally at room temperature.
• Keep away from direct heat sources such as radiators, fires, or tumble dryers.

Disinfection

• Use non-aggressive, alcohol-free products suitable for synthetic footwear, on the lining and insock.
• Test on a hidden area first.

Maintenance and overhaul

• Inspect regularly for excessive wear, worn cleats, sole separation, puncture damage, upper damage, or damaged hooks and laces.
• Replace immediately if protective performance may be compromised, or after a heavy impact to the toe.
• This boot is of cemented construction and is not designed to be resoled.
• Replace the insock only with a comparable Gaucho Ninja insock.

Storage

• Store in a cool, dry, ventilated place, ideally in the original box.
• Avoid prolonged sunlight, humidity, or crushing loads.
• Shelf life: 5 years from date of manufacture when stored unused at 15–25 °C and below 60 % RH.

This PPE is designed to help protect against:

• Impact and crushing injuries to toes
• Underfoot penetration from sharp objects
• Slipping on occupational surfaces
• Static build-up discharge
• Water entering the footwear in wet working conditions
• Shock to the heel when walking and stepping down
• Outsole damage from contact with oils and fuels
