The joints make the body flexible
It is outmost important to take care of joints and muscles throughout your life. Joints and muscles work together for you to be able to move. What you need to do it to make sure that they can do their job for you as long as possible, without getting tired.
The joints sit where two or more bones in the skeleton meet and allow the bones to move. Without joints, we would not be able to bend or stretch the body. Joints are movable connections between two and more bones in the skeleton. The joint surfaces are covered with articular cartilage that is hard and consists of a support tissue, which means that the surfaces can slide against each other and minimize the risk of them being worn out.
The muscles give strength
We have different types of muscles, but they can all contract, stretch, tense or relax. The skeletal muscles are attached to the skeleton and are muscles we can control. The skeletal muscles have two tendons that are attached to each side of a joint, so the joint moves when you tense the muscle and then relax. Skeletons, muscles and joints work together to allow you to move. Muscles and joints working together is a prerequisite for your body to be able to stay active and get strength.
Our technology supports your body and supports your muscles and joints
Stinaa.J has developed shoes and orthopedic insoles that work with and on your body. They help your feet move in their most natural way possible. The goal is that the position and angles your feet and body land in with every step (or while standing) are correct from the biomechanical perspective.
We have chosen to call our second global patent “5-Bar System” because of its five barriers, that are the core of the 5-bar insole.
The first three horisontal bars support the foot’s three arches. They help the foot to move and shock-absorb in its most natural way and prevent the feet from ending up in extreme positions that can cause injury.
The other two vertical bars create stability. They straighten the feet, knees and hips so that the pressure load distributes evenly, from the feet and all the way up to the back. In this way the body is in neutral position when you are still or complete a step – the balance between effort and rest is achieved.
When it comes to the shape of our 5-bar insole, as with 3-step insoles – it is based on millions of 3D-scanned feet from all over the world. Most likely – they fit you just perfectly.
The insole has five different layers, each with its unique qualities and function:
The top material
Here we have chosen a perforated material that is able to breathe and transport moisture from the foot's 250,000 sweat glands. The material also prevents the risk of unnecessary frictional damages (blisters).
Memory foam
Another medical Poron with a special density. The material reacts to the pressure and shapes itself after the shape of the feet. It has a reaction time of three seconds, which means that it has time to return to its original shape while the foot is in the air.
The shock-absorbing layer
We have chosen to use medical Poron, frequently used in the space industry. Great at absorbing shocks for you who appreciate the movement.
The five bars
The core of the insole. Provide stability, and ensure that the feet and body land in the correct neutral position. The bars support all three arches during standing or moving. They give the feet some good exercise and when you use the 5-bar insoles regularly you strengthen your feet´s muscles. The feet get maximum relief, shock absorption, and stability. A unique product by Stinaa.J, with a global patent.
The bottom
Made to withstand great stress and wear. Perfect for active lifestyle as it is easy for the sand or other loose particles to enter the shoe when you walk or run.
