ELTEN uses new materials with the latest manufacturing and processing technologies for cushioning, including Infinergy from BASF and Supercritical Foam (SCF). Conventional EVA is light and flexible – but it has a decisive disadvantage: over time, it loses its cushioning properties. This process, known as degradation, results in shoes feeling much harder after a few months. The original softness and resilience are lost, which not only affects wearer comfort, but also increases physical strain. Joints, the back and the muscles are particularly affected – in other words, precisely the areas that are already under a lot of pressure in everyday working life. Anyone who is on their feet every day, for example as an electrician on a construction site, a warehouse worker in a dispatch center, a nurse in a hospital or an employee in industrial production, relies on safety shoes that keep them protected and comfortable all day long.
This is where SCF makes the difference. Although the material is also based on EVA, among other things, it is produced using a completely new process. Instead of chemical propellants, SCF uses environmentally friendly gases such as carbon dioxide or nitrogen. These are introduced into the base material under precisely controlled pressure and temperature conditions. The result is a foam with a particularly fine and uniform cell structure, which is not only lighter but also offers significantly greater rebound and resilience. This means that cushioning is maintained over a much longer period of time – even during intensive use. This supports joint health in the long term.
This joint-friendly effect is particularly beneficial on hard surfaces, when standing for long periods of time and when there is a lot of movement – an essential factor that is often overlooked when choosing safety footwear.
The advantages of this technology are not just theoretical. Anyone who is on their feet every day benefits from the improved energy return and cushioning that noticeably relieves pressure on the knees, back and hips. The shoes still feel comfortable even after hours, muscle fatigue is reduced, and the risk of long-term issues is minimized. This is a decisive factor for health and well-being, especially in professions involving a lot of movement or long periods of standing.
ELTEN currently uses SCF in all models in the TRANSFOAMERS series – including:
- JORAN BOA® YELLOW Low ESD S3L: A lightweight, metal-free safety shoe with SCF midsole and slip-resistant rubber sole. Ideal for anyone who is on the move a lot
- BATIS BOA® BLACK-RED Low ESD S1PL: Sporty, lightweight and with breathable textile material – perfect for dry working environments
- LIVAS BLACK-BLUE Low ESD S1PL: The safety shoe combines an SCF midsole with a slip-resistant rubber outsole and stands out with an innovative material mix for maximum wearing comfort.
These models of different protection classes show that SCF is not just a technical feature, but a real added value for everyday working life. The shoes still feel comfortable even after hours, muscle fatigue is reduced and the risk of long-term discomfort is lowered.
Supercritical Foam is a step forward that is noticeable with every step. Anyone who spends a lot of time on their feet will feel the difference – and won’t want to go anywhere without it anymore.
