Komisafe PU Safety Shoes: 3 Years of R&D, One Uncompromising Range

When JMDi Safezone set out to build a premium PU safety shoe range, we didn't rush it. Nearly three years of research and development went into perfecting the Komisafe line — from sole formulations and last geometry to material sourcing and ISI certification. The result is a range of PU leather safety shoes that we believe sets a new standard for comfort, durability, and protection in Indian industrial footwear.

Why PU? The Science Behind the Sole

Polyurethane (PU) has become the gold standard for safety shoe soles in demanding industrial environments — and for good reason. Unlike PVC, which is a rigid thermoplastic, PU is a thermoset material that can be engineered for specific density, hardness, and flexibility characteristics.

In Komisafe shoes, we use a double-density PU sole — two layers of polyurethane with different properties injected in a single moulding process:

Inner Layer (Low Density)

Softer, lighter PU that sits directly under the foot. This layer provides cushioning, shock absorption, and energy return — critical for workers on their feet for 8–12 hour shifts. It reduces fatigue and absorbs the impact of walking on hard concrete and steel surfaces.

Outer Layer (High Density)

Harder, denser PU that forms the outsole — the part that contacts the ground. This layer provides abrasion resistance, slip resistance, and chemical resistance. It's engineered to withstand oil, acid, and alkali exposure while maintaining grip on wet and oily surfaces.

The result is a sole that is lighter than PVC, more comfortable than rubber, and significantly more durable than single-density alternatives. In our testing, double-density PU soles last 2–3 times longer than standard PVC soles under equivalent wear conditions.

3 Years of R&D: Getting It Right

Launching the Komisafe range wasn't a matter of simply switching from PVC to PU. It required a fundamental rethinking of our manufacturing process, material science, and product design.

For nearly three years before the first Komisafe shoe reached the market, our team worked on:

  • PU Formulation Development

    Testing dozens of polyurethane formulations to find the right balance of density, hardness, and flexibility for Indian working conditions — extreme heat, cold warehouse floors, and oil-soaked factory surfaces.

  • Last Design & Ergonomics

    Developing new shoe lasts (moulds) specifically shaped for Indian foot anatomy. We studied foot pressure distribution patterns during walking, standing, and climbing to optimise comfort for long shifts.

  • Injection Moulding Calibration

    Setting up and fine-tuning double-density PU injection moulding machines — getting the timing, temperature, and pressure exactly right so both PU layers bond perfectly without delamination.

  • Leather & Upper Material Sourcing

    Testing buffalo leather grades from multiple tanneries for breathability, tear strength, and abrasion resistance. Selecting stitching patterns and thread specifications for maximum durability.

  • ISI Certification Process

    Working with the Bureau of Indian Standards for IS 15298:2024 certification — submitting samples, undergoing factory audits, and passing all required performance tests including 200J toe impact, 15kN compression, sole flexing, and electrical resistance.

The result of this extended development period is a range that we stand behind completely. Every Komisafe shoe carries the ISI mark under IS 15298:2024 — and every pair is manufactured at our own factory in Sonipat, Haryana, where we control every step of the process.

The Komisafe Range: Three Models, Every Need

Each Komisafe model is designed for a specific use case — but all three share the same double-density PU sole technology, ISI certification, and 200J steel toe protection.

1

Komisafe Aviator

Lightweight Ankle Boot

The Aviator is built for workers who need protection without the weight. A low-cut ankle design makes it easy to wear for extended shifts, while the double-density PU sole provides cushioning and shock absorption. Ideal for manufacturing plants, logistics operations, and warehouse environments where agility and comfort matter as much as safety.

Low-cut ankle design for ease of movement
Double-density PU sole — soft inner layer for cushioning, hard outer for durability
Steel toe cap rated for 200J impact
Oil, acid, and chemical resistant sole
Breathable leather upper with padded collar
Heat-resistant sole up to 120°C
2

Komisafe Knight

Heavy-Duty High-Ankle Boot

The Knight is our heavy-duty workhorse — a high-ankle boot designed for the most demanding work environments. The extended ankle coverage provides additional protection against debris, sparks, and accidental impacts. The reinforced upper and aggressive sole tread make it the go-to choice for construction sites, steel plants, and mining operations.

High-ankle design for superior ankle support and protection
Double-density PU sole with deep-tread pattern for maximum grip
Steel toe cap rated for 200J impact and 15kN compression
Heat-resistant sole up to 120°C contact
Reinforced leather upper with padded tongue and collar
ESD — Electrical Resistant (0.1 to 100 MegaOhm)
3

Komisafe Rocky

Rugged All-Terrain Boot

The Rocky is our all-terrain performer — engineered for workers who move between different surfaces and conditions throughout the day. Whether it's a muddy construction site, a slippery factory floor, or rough outdoor terrain, the Rocky's aggressive sole pattern and reinforced construction handle it all. It's the most versatile boot in the Komisafe range.

All-terrain sole pattern for grip on varied surfaces
Double-density PU sole with enhanced shock absorption
Steel toe cap rated for 200J impact
Buffalo leather upper with foam-padded collar and tongue
Padded collar and cushioned insole for all-day comfort
Suitable for both indoor and outdoor work environments

Komisafe vs Komico: Which Is Right for You?

Both brands are manufactured by JMDi Safezone and carry ISI certification. The choice depends on your work environment and priorities.
