The Technology
of βBuiltβ
Every technology in SPIEZ began the same way β with a problem no existing solution could solve. Developed, tested, and refined until the result was undeniable.
01 β WUNDER GRIPβ’ Β· OUTSOLE SYSTEM
Wunder Gripβ’
Proprietary multi-directional traction. Tested where certifications stop β on the surfaces where people actually work.
ORIGIN STORY Β· THE PROBLEM
Kitchen floors fail every existing slip standard by design β covered in oil emulsions, not water. Standard certifications test with water. We tested with what's actually there.
Wunder Gripβ’ began as a proprietary compound and tread geometry developed specifically for oleic-acid contaminated surfaces. The result performed at levels no off-the-shelf outsole could match. That was the beginning of our own standard.
βThe grip that carries the shift β on every surface it was never tested on.β
TECHNICAL SPECIFICATIONS
APPLIED IN
Multi-Surface Validated
Tested on ceramic tile, polished steel, wet concrete, and oily kitchen surfaces β the four conditions existing certifications don't combine.
Compound Engineering
The rubber compound is tuned at the molecular level to maximise friction coefficient across both polar and non-polar liquid contamination.
Durability Protocol
Grip performance validated to maintain above 85% effectiveness through a minimum of 1,500 hours of active wear β tested on a mechanical abrasion rig.

02 β SHIELDXβ’ Β· PROTECTION ARCHITECTURE
ShieldXβ’
Composite protection system. Lighter than steel. Non-conductive. Engineered as a single architecture, not a collection of parts.
ORIGIN STORY Β· THE PROBLEM
Steel toes pass every impact test. They also conduct electricity, add 180g of dead weight, and trigger airport security. The standard solution solved the wrong problem.
ShieldXβ’ uses a carbon-composite lattice structure derived from aerospace applications. The same geometry used to absorb crash forces in aircraft components β applied to where your foot meets a falling object.
βProtection that was designed from the inside out β not assembled from catalogue components.β
TECHNICAL SPECIFICATIONS
APPLIED IN
Aerospace-Derived Structure
The carbon composite lattice geometry originates in aircraft fuselage design β where weight-to-strength ratio under impact is a matter of life and safety.
Airport Transparency
Carbon composite passes through X-ray detection without triggering metal alerts. The only safety-rated work shoe designed for professionals who travel.
Integrated System
Toe box, midsole plate, and heel counter are engineered as a unified load-distribution structure β not independently sourced and assembled.

03 β BERNCOREβ’ Β· CUSHIONING SYSTEM
BernCoreβ’
Adaptive midsole cushioning inspired by the Aare River's hydraulic equilibrium. Never too soft. Never too hard. The same response at hour ten as at hour one.
ORIGIN STORY Β· THE INSIGHT
The Aare River maintains consistent hydraulic pressure across variable terrain through distributed energy absorption. That principle β not a foam formulation β became the design brief.
Most midsoles degrade in stiffness after 4β6 hours of continuous load. BernCoreβ’ uses a zone-density architecture that distributes compression across the full footbed β preventing the localized fatigue that causes pain after long shifts.
βDesigned for hour twelve. So hour one feels the same.β
TECHNICAL SPECIFICATIONS
APPLIED IN
Zone-Density Architecture
Three distinct density zones β heel, arch, and forefoot β each tuned to the pressure distribution and motion type most common in professional work environments.
Shift-Length Testing
Performance tested in 12-hour continuous load simulations β not the 1-hour industry standard. Because real shifts don't end at hour one.
Fatigue Reduction
Independent testing shows 34% reduction in lower limb fatigue markers at hour eight compared to standard EVA midsole construction in comparable footwear.

04 β ARC-Hβ’ SUPPORT Β· ARCH & HEEL SYSTEM
ARC-Hβ’ Support
Biomechanically engineered arch and heel support. Distributes plantar load across the full footbed. Reduces fatigue at the source β not after it happens.
ORIGIN STORY Β· THE PROBLEM
Plantar fasciitis, heel pain, and arch collapse account for over 40% of occupational foot injuries. Most insoles address symptoms. ARC-Hβ’ addresses the mechanics that cause them.
Derived from orthopedic load-mapping data across 12 professional environments, ARC-Hβ’ is a dual-density arch bridge and heel cup system built directly into the shoe's construction β not added after the fact as a removable insert.
βBuilt into the shoe, not dropped in. Because your support system shouldn't be optional.β
TECHNICAL SPECIFICATIONS
APPLIED IN
Orthopedic Load Mapping
ARC-Hβ’ geometry was derived from pressure-mapping data collected across 12 professional environments β healthcare, construction, food service β to reflect real-world plantar load distribution, not lab averages.
Integrated Construction
ARC-Hβ’ is not a removable insole. The arch bridge and heel cup are built into the midsole's structural layer β providing consistent support that cannot compress, shift, or be accidentally removed.
Dual-Density System
Two distinct zones β a firmer arch bridge for lateral stability and a softer heel cup for impact absorption β work together as a single biomechanical system rather than competing for compliance.

05 β THE PROOF
Not certified because we had to.
Safety certifications aren't a checkbox at SPIEZ. They're the minimum the people wearing our shoes have the right to expect. Dual certified β American and European standards both.
ASTM F2413 β American Safety Standard
Impact resistance, compression protection, metatarsal guard. The full North American occupational footwear standard.
EN ISO 20345 β European Safety Standard
The EU's highest occupational footwear classification. Required on construction sites across 27 countries.
Slip Resistance Class SRC
Highest slip resistance classification β ceramic tile with SLS solution and steel floor with glycerol.
Electrostatic Discharge Protection
Tested to prevent electrostatic buildup β critical in electronics manufacturing and explosive environments.
TECHNOLOGY IN ACTION
Built for the
ones who build.
Every technology. Both certifications. Built for the shift, not the shelf.
