We use alternative Gravity® outsoles in the footwear program according to target customer-group and expected use. You will find information on type of outsole used in the information included in the product-pages.
- Gravity® G-Sport III - 209 grams (size 42)
This is a very light and sporty outsole, perfect for all inside work in various professions where light and energy-absorbing footwear is needed. Suitable outside during three of the Nordic seasons.
- Gravity® G-III - 243 grams (size 42)
This is a very stable and medium weight sole with a pattern that provides good grip and that works well in various environments and on different surfaces throughout the year.
- Gravity® IPR - 236 gram (size 42)
This is an innovative outer sole included the unique energy-absorbing material IP (Injection Phylon) in the midsole. Many describe this sole as "walking on clouds".
- Gravity® TRX III - 266 grams (size 42)
This is a durable and powerful sole with a pattern that provides a very strong grip. Unique to the sole is the "trunk" in the front which is an integral part of the outer sole. This provides extra protection at the front and is an advantage for anyone who has work leading to extra wear and tear in the front of the shoes. On the winter model K2, Gravity® TRX III comes in combination with "Ice-Grip" in the central part of the grip zone. This for providing extra safety on slippery surfaces during winter and with the variations of temperatures in the Nordic climate zone.
This is a presentation on how Gravity® soles are constructed and what is called "cemented construction". The design principles are the same for all styles in the Ironsteel footwear program. Shown above is the Gravity® TRX III with its bottom and top sides. Here in white colour, is the light-weight Phylon midsole, including a technically integrated design to ensure antistatic properties. On top of the midsole is a non-metallic anti-penetration sole. This protects the user from penetration of sharp objects, i.e. nails. The removable shock absorbing footbed incl. Poron® provides cushioning and comfort. The cap that secures the toes is specially adapted to each Gravity® sole design to provide optimal fit and resistance.
