CONSTRUCTION
Secure, flexible construction
Strobel construction
joins the upper to a flexible insole layer, creating a sock‑like base
that bends with your foot for natural movement while still supporting it
over long shifts.- Sidewall stitching all around
then locks the upper to the sole along the full perimeter, giving a
very secure bond that resists delamination and keeps the shoe stable
under load, ladders and uneven ground. - Strong yet supple:
this combination of strobel + sidewall stitching delivers the
structural integrity HSE teams look for in work footwear, without
sacrificing the barefoot flexibility and ground feel that make Sneaky
Ninjas so easy on the body.
CARE Instructions
Care instructions – microfiber nubuck
- Everyday cleaning
Brush off dry dust and dirt with a soft shoe brush or a clean, dry cloth. For marks, use a slightly damp cloth with a small amount of mild soap, then wipe again with clean water and let air dry away from direct heat. - Dealing with stains
For stubborn spots, use a dedicated microfiber / synthetic nubuck cleaner, following the product instructions, and always test first on a small hidden area. Avoid harsh chemicals, bleach, or solvent‑based cleaners, as these can damage the fibres and finish. - Water and stain protection
Once clean and dry, apply a spray

Movement & Balance
Designed Around the Body
Barefoot geometry allows the foot to move as it was designed to — with natural alignment, balance, and feedback from the ground.
By avoiding raised heels, excessive cushioning, and narrow toe shapes, this collection supports:
-Natural posture
-Even pressure distribution
-Reduced restriction during movement
Comfort here comes from balance, not padding.
The Sacred Geometry sole applies this natural logic beneath the foot, using proportion and flow to distribute pressure evenly and support movement without force or correction.
This is not decoration. It is structure.
Certified to EN ISO 20345:2022 & ASTM 2413-24

Designed for professionals
Sneaky Ninjas 2.0 are safety trainers designed for professional environments
where certified toe protection, slip resistance, puncture resistance,
antistatic control and oil / hot‑contact resistance are required, while
maintaining a minimalist, all‑black appearance.
Typical work environments
-Airports and aviation
Ground crew, baggage handlers, ramp agents, aircraft cleaning teams and aviation maintenance working around fuels, vehicles, equipment and metal detectors.- -Warehousing, logistics and distribution
Forklift drivers, pickers and packers, loading‑bay staff, parcel and courier
hubs operating on polished concrete with dust, spills and occasional sharp debris. - -Workshops, garages and light engineering
Mechanics, fabricators, body‑shop staff and technicians working around tools, metal offcuts, oils and lubricants. - -Manufacturing and assembly (light to medium duty)
Production line workers, assemblers and maintenance teams where toe protection, slip resistance and puncture resistance are required. - -Electronics, data and controlled environments (SD10)
Electronics manufacturing, repair labs, control rooms and data centres where static‑dissipative footwear is specified. - -Facilities, cleaning and building maintenance
Janitorial teams, caretakers and facilities staff working on wet or freshly
cleaned floors in offices, schools, hospitals and public buildings. - -Food production and catering back‑of‑house
Industrial kitchens and food processing areas that require closed, slip‑resistant safety footwear and exposure to oils and hot contact is likely. - -Security, institutional and public‑facing roles
Security staff, stewards and institutional workers who need quiet, all‑black safety footwear that blends with uniform while offering certified protection. - -Events, film and live production crews
Stagehands, riggers, AV and lighting crews, and production teams who need discreet, all‑black safety trainers suitable for arenas, theatres, festivals and
studios. - -Healthcare and similar settings requiring all‑black safety shoes
Non‑clinical staff and support roles in organisations such as the NHS (where permitted by local policy), including porters, estates and facilities teams who must wear all‑black safety footwear. - -Light construction trades and site visits
Electricians, plumbers, HVAC technicians, surveyors and site managers who need certified safety footwear for mostly indoor or finished‑surface work, without the bulk of a traditional boot.
Not intended for heavy‑duty construction, extreme impact or chainsaw use. Always follow your workplace PPE requirements.
Frequently asked questions

-
They are ideal for workers who want certified safety footwear that fits like a barefoot shoe – from airport and warehouse staff to tradespeople, logistics teams and minimalist shoe wearers who refuse to compromise on natural movement.
-
S3 is an EN ISO 20345 category designed around conventional heeled safety boots, where part of the standard (the E marking) is energy absorption in the heel area for that raised‑heel construction. That makes sense for traditional, thicker‑heeled boots, but it assumes the foot is sitting on a built‑up heel rather than moving in a flat, barefoot way.
Sneaky Ninjas 2.0 are certified to EN 20345 SB PS SRO A FO HO plus ASTM 2413 I/C PR SRO SD10, so they cover toe protection, antistatic performance, puncture resistance, slip resistance, fuel‑oil resistance, hot‑contact resistance and static‑dissipative properties, without a raised heel. Instead of relying on heel “E” energy absorption, they use a zero‑drop, flexible sole and wide barefoot platform so your whole foot and body stack naturally, distributing impact through natural movement rather than through a built‑up heel block.
