Technical description of MEDICOVI® -D40

D40 consists of a soft EVA-upper sole and an underlying sensory water filled massage sole. Before use the two soles are glued together by the self attaching glue that is on the surface of the water filled sensory massage sole.

The soft EVA-upper sole

The soft EVA-sole is made of an anti fungicide material. On the sole surface facing the foot the EVA-sole has been applied with a very strong fabric that has been treated with AEGIS Microbe Shield.

 

The sensory water filled massage sole

A vital condition for the sensory water filled sole to give sensory massage is that when the sole is exposed to pressure loads it is able to build up a dynamic hydraulic pressure under the foot bones. This means that the sole has to be strong enough to carry the body's weight through the dynamic hydraulic water pressure inside the sole.

During construction of the water filled sensory massage sole a number of specially developed materials has been used. The patented lamination provides the sole with excellent strength and stability which is necessary for the sensory massage.

 

The sole contains water as water is fast flowing, this being an absolute prerequisite for affecting the sensory massage and the hydraulic pressure equalization.

To further optimize the water movement the welding of the sole has been done by a special welding method that creates a hollow space between the two foils ensuring optimal water movement. Furthermore the sole is supplied with welding patterns on the sole surface that controls the water movement ensuring that the sole mainly builds up pressure equalizing water cushions under the heel and forefoot.

The underside of the sensory water filled massage sole is provided with a friction film that ensures that the sole stays put in the shoe.

The laminates that make up the sole must invariably follow the fast movement of the water under the huge dynamic hydraulic pressure and this movement causes wear and tear on the laminates. At a certain stage, the wear and tear does cause tiny holes in the laminates and water will evaporate.

Shock-absorption and pressure relief in the sensory water filled massage sole

In the heel the sensory water filled massage sole MEDICOVI® -D50 has a welding pattern that functions as double valve that regulates the speed that water under pressure can flow freely under the forefoot. The double heel valve provides an affective shock-absorption and pressure relief of the heel bone, especially at low speeds, where the build in shock-absorption in shoes normally don't work.

 

When the soles heel surface is exposed to pressure load it will take time for the water to pass through the double heel valve, which will increase the collision time. At the same time the pressure on the heel will raise the hydraulic pressure in the water that has yet to pass through the double heel valve. The hydraulic pressure will distribute the pressure force from the heel to a larger surface of the heel cushion, making the collision area larger. The raise of the collision time and the collision area creates the shock-absorption in sensory water filled massage sole.

The double heel valve also slows down the water movement when the forefoot is exposed to pressure loads and causes the water to return back towards the heel. The double heel valve herby provides powerful effective shock- absorption and great pressure relief to the forefoot.

The double heel valves, slowing down of the water in combination with the inserted point barriers creates a water cushion under the forefoot and especially under the ball of the forefoot. The water cushion prolongs the collision time, at the same time the counter pressure in the water cushion will expand the pressure surface up against the ball of the forefoot (Collision surface), creating powerful pressure relief to the ball of the forefoot.
When you stand it is the heel and forefoot that is exposed to the biggest pressure loads.

That is why the double heel valve and the inserted point barriers are constructed is such a way that they create a water cushion that is mainly concentrated under the heel and the ball of the forefoot.

The hydraulic pressure cushion under the heel and forefoot occurs when the water under pressure loads from the foot becomes enclosed inside the strong inelastic foils with the double heel valve and the inserted point barriers. As mentioned earlier it is the powerful force in the strong inelastic foils that enables the build up of the necessary hydraulic pressure creating the large pressure relieving carrying surfaces under the heel and forefoot and for the sensory massage.

Even when we are stand still every little movement of the body will change the pressure loads that the foot will transfer to the sole surface. In a regular shoe these many little body changes will not do anything significantly with the pressure loads under the heel cushion and the ball of the forefoot.

By placing the water filled sensory massage sole in the shoe the sole will create a hydraulic dynamical pressure cushion between the foot and shoe. The hydraulic pressure patterns in the sole will react to every single little change of the body's position and create/provoke new and different pressure patterns under the foot. Especially under the forefoot the constant change of carrying surfaces will reduce the time- and pressure loads on sore and painful areas.

It is the constant varying hydraulic pressure patterns in the sole that creates the sensory massage. Every time the body changes its position the pressure load form the foot against the sole will change, creating yet another new hydraulic pressure pattern in the sole. The new hydraulic pressure pattern in the sole will provoke/force the foot to change foot position more frequently.

The body's balance system will respond to the new foot position by activating the calf and thigh muscles which will make the body change position.

As mentioned above the sensory massage will create a great balance uncertainty unless the system is restricted. If you stand in a waterbed where there is no water restriction is would be very difficult to keep your balance. Due to the double heel valve and the precisely measured water amount in the sensory water filled massage sole the movement of the water is regulated, making sure that the water movements under the foot feels stimulating and comfortable while at the same time keeping the sensory massaging effect.

Size of the sole and shoe

The length of MEDICOVI® -D40 must correspond to the foot. Before opening the vacuum pack with the sensory water filled massage soles it is recommended that one checks the length of the sole by placing the soft EVA-upper sole on the floor and then placing the foot on top of the sole.  

MEDICOVI® -D40 is 4,5 mm thick. The shoe should be large enough for the foot to be able to move once the sole has been inserted. The MEDICOVI® -D40 sole is made to fit two shoe sizes.

The toe piece may be cut to the smaller shoe size with scissors. Fore example from size 43 to size 42. In open shoes without heels, the MEDICOVI® -D40 must be securely attached to the inside bottom of the shoe. In shoes without a heel back a piece of Velcro can be placed on the bottom of MEDICOVI® -D40 across the sole over the welding pattern just after the heel.

Getting used to the soles

MEDICOVI® -D40 increases circulation in the feet and legs through strong activation of the sole of the foot as well as the calf and foot muscles. Sore muscles may be experienced at first until a reasonable state of fitness has been achieved. Some people may initially think that the soles contain unequal amounts of water. The reason for this is, however, that our feet have different tolerance levels and this sensation will quickly disappear. Anyone suffering from dizziness may experience problems with the sole due to the continual movement of the foot. However is should be noticed that clinical tests have showed that the soles helps to improve posture and balance.

 

Life span of the soles

With normal use the soles will work for about one year. In order to achieve maximum relief from the soles it is therefore recommended that the soles be replaced at least once a year.

It is strongly recommended that people suffering from diabetes examine the function of the soles and checks the shoe for impurities every single day.
