FAQ

Safety shoes provide foot protection on various parameters like sharp objects, falling heavy objects, electrical hazards, slipping etc.

It depends on the application for which you would need one, for which our safety expert / safety shoe mobile application can guide you.

We do have a size chart which can guide you to pick a size for yourself and others. Whereas for corporate purchase we recommend a size kit trial before placing final orders.

Yes, different brands use last sizes (Last is like a mould that gives the shoe its 3-Dimensional figure). For a better fit it is recommended to try out shoes when switching from one brand to another.

IS -Indian Standards, Safety shoe are according to IS 15298 Standard
IS- Indian Standards, PVC safety shoe are according to 1S 14544 Standard
EN - European Standards, Safety shoe are according to IS 20345 Standard

Ergonomics in safety shoes is important because it ensures proper support, reduces fatigue, and prevents injuries by aligning with the natural movement and structure of the feet.

Being lightweight is important for comfort, but ergonomics is also crucial as it ensures proper support, reduces fatigue, and prevents injuries

Shoe sole composition comes in PVC, Rubber, Polyurethane & Thermoplastic-Polyurethane.

Poly-Urethane is a mixture of Polyol and Iso-cyanite and is the most widely used soles in safety shoe.

We are one of the largest consumers of Poly-Urethane in safety shoes segment in India, buying from the World-renowned German-based BASF.

Single density PU, Double density PU-PU, Double density PU-TPU, Double density PU-Rubber, Triple density nitrile, Nitrile Rubber, PVC

Thermoplastic polyurethane (TPU) is any of a class of polyurethane plastics.

Increased elasticity, resistance to oil, grease and abrasion, better performance in changing weather conditions.

Increased temperature resistance and traction. Up to 300°C

Molecules of vinyl chloride monomers combine to make long chain molecules of polyvinyl chloride. This synthetic polymer is relatively cheap and easy to mold.

Is a synthetic rubber copolymer of acrylonitrile (ACN) and butadiene, provides increased puncture and temperature resistance.

Please refer to ACME’s comparison charts

We have charts comparing different sole types on various parameters.

There are regular non-woven antistatic insoles, non-woven non-anti-static insoles and carbon insoles basis of the application of shoes.

The dynamic arch design adapts to all foot shapes redistributing heel, ball and toe pressure for maximum support and comfort.

Anti Perforation Insole protects the foot from injury from sharp objects by means of inserting a level of protection in-between the insole. There are two options: Kevlar that is much lighter and capable of protecting 100% of the foot surface as compared to 85% by the classic steel mid-plate, which is metallic and thus heavier.

CS PRINT & OIL PULL UP Leather

Leather types which are made from PVC or PU with bonded lamination backing.

The full name of the Micro-fibre leather is "microfiber-reinforced PU leather", which is an artificial leather made of PU leather (polyurethane leather) added with microfiber, and its toughness, abrasion resistance and air permeability are improved. It is completely biodegradable and chrome free.

All leather prints are available with us in water-repellant variants. It is called DIN leather and protects the shoe against exposure to water up to 60 minutes. All shoes marked from S2 upwards have water-repellent uppers.

Sole technology with three distinct layers: Midsole1, Midsole2, and Outsole, each offering varying densities. This design enhances stability, comfort, and safety by providing targeted cushioning, support, and durability.

High-performance responsive E-TPU material, predominantly composed of closed-cell bead foam in expanded thermoplastic polyurethane (E-TPU), ensures exceptional durability and cushioning. Another advantage is the material's exceptional long-term durability, significantly outperforming conventional midsole materials.

Provides a high-strength and high-elasticity alternative. Its superior energy return and lightweight nature deliver next-level comfort and flexibility.

It is recommended for extra comfort because they conform to the shape of your feet, providing personalized support and cushioning that reduces pressure and enhances overall comfort.

Fasteners are clipped holes or D-Rings through which laces are passed for fastening.

HONEYCOMB, CAMBRELLE & SPACER. Spacer is superior to the former two as it has foam padding in between the two linings.

Thermoplastic is a plastic material used in counter. The shoe retains its shape and function and is more durable and resistant to wear and tear.

Toe spring is the elevation of your shoe's toe box above the ground or supporting surface.

Wrap the measuring tape around your foot, so that you would basically stand on the tape with your inner ball (the one behind your big toe). The tape should move straight across your foot. It may wrap around your small toe.

It is a metal cap that is strategically integrated in the shoe to protect your toes from falling objects.

Depending on toe-cap specification, it can provide impact resistance of 200J, 140J or 100Joules
*200 Joules= An object weighing 20 kg falling on ground from a height of 1 meter / an object of 2 kg falling from a height of 10 meters

TESTS:
On Impact- there should be min. 14 mm distance between the foot and the cap for size 8
On compression- there should be min. 14 mm distance between the foot and the cap for size 8

It is a non-metal toe-cap, which could be made of Kevlar, carbon fiber or plastic.

Both may provide the same level of protection, though non-steel toe-caps are much lighter.

Where metal free shoe is required like airport security etc., or where probability of shock is more, since metal is good conductor of electricity the wearer is more prone to shock if he is wearing a metal toe-cap.

Gumboot

Shoe not containing any metal fixtures- be it fasteners, mid-plate or toe-cap.

Yes, Slip-Ons are available.

Because they tend to stay tied better, distribute pressure more evenly, and are less likely to come undone.

Shoes can be either Antistatic, ESD or Shockproof

Shoes allowing Electro Static Discharge between ranges: 105 - 35*106 Ohms

Shoes allowing Electro Static Discharge between ranges: 105 -109 Ohms

Slip resistance (SR): This additional requirement tests the slip resistance of the safety shoes on ceramic tiles with glycerine. When the heel slides forward, a coefficient of friction of >= 0.19 mm is allowed. When the front part of the shoe slides backwards, a coefficient of friction of >= 0.22 mm is allowed.

A coefficient of friction is a value that shows the relationship between the force of friction between two objects and the normal reaction between the objects that are involved.

It is the time when the shoes are not in use, packed & placed on shelf.

Dependent on factors like density, composition and size.

• a. Detachment of sole from upper
• b. Development of Cracks the sole
• c. Abrasion of sole

Development of Cracks the sole

Scraping or wearing of sole

Sustainable footwear is designed and produced with minimal environmental impact, using eco-friendly materials and processes to reduce waste and promote recyclability.

Due to the use of imported raw materials, collaboration with international designers, and valid EN certifications, our products ensure superior quality and compliance with global standards.

Proper leather shoe treatment not only makes your shoes look good, but it also preserves the natural material, adding to their life. Without proper conditioning and care, leather dries out, eventually cracking and falling apart, leaving your shoes and boots an unsightly mess. Throwing a coat of shoe polish on them now again does help. But in order to maintain the supple appearance of your leather goods, you must keep them clean, conditioned, polished, and weatherproofed

Direct Injection Process, is a process of soling shoes under highly controlled parameters. We at ACME use the most advanced German-make DESMA machines to carry out the process of injection. To know more about this you may refer to the datasheet on DIP shoes.

Pouring again is a method for soling, which on the contrary is carried out in a more open and less controlled environment. Shoes produced are a level inferior than those done on DIP process.
