During walking and running, forces equivalent to two or three times the body’s weight are exerted on the soles of the feet. In long runs, the accumulated pressure on the foot can reach very high numbers, equivalent to the weight of 117 tons per kilometer (for an average runner weighing 70 kg).
The load exerted on the foot during running and walking is primarily applied to the heel, as in most athletes, the first contact with the ground is made with this part of the foot. This fact further increases the risk of sports injuries and damage to the skeletal and muscular systems.
Given these data, the need arises for the use of special insoles during engagement in “repetitive sport,” as activities in which one motion is repeated over and over for a long time are called.

Sport insoles designed for running and intensive walking are manufactured in such a way that they contribute to the reduction of tension created by the effort and to the prevention of injuries to the skeletal and muscular systems. As a result, they also delay muscle fatigue during activity, and contribute to enhanced performance.
Insoles for walking and hiking
These sport insoles are intended for high-intensity walking and long journeys under challenging walking conditions. They are produced in a multi-layer structure that combines several materials with varying degrees of softness, resulting in comfort and flexibility, and allowing for efficient and correct movement of the foot. In these insoles, the foot pad area is softer than the heel area, which optimally reduces the load during the walking cycle when the pressure shifts from the heel to the front of the foot.
Running insoles
Sport insoles intended for running are sometimes made from harder materials, in order to create a correct distribution of forces during running. These insoles cushion the front area of the foot to optimize the force distribution during running, while the first and fifth toe areas are light and slightly raised to avoid creating excess load that could lead to the formation of calluses and blisters. The support these insoles provide to the foot leads to the development of a physiological balance among different muscle groups.
With the help of sport insoles intended for running, both professional and amateur runners and sprinters can prepare their bodies for the load exerted during running and stimulate less active muscles. This can also reduce instances of ankle pronation or supination and ensure that the joints function properly during exertion.
SPINFEET – Specialized Sport Insoles for Cycling and Spinning
The SPINFEET insoles are specialized sport insoles developed by the Avidor network, specifically designed for cycling and spinning workouts. These insoles were created in a size that allows them to be easily inserted into a riding shoe, and are designed to accommodate the constant and prolonged pressure on the foot during pedaling, which sometimes causes a sensation of numbness in the feet.
Many cyclists experience this numbness even after correctly adjusting their bicycles (seat height, distance from the handlebars, cleat direction, etc.). How can this issue be resolved and the sensation of numbness eliminated? By reducing the pressure from the nerve paths in the foot area, a function performed by the SPINFEET insoles which include a supportive pad in the toe pad area, precisely for this purpose.
The SPINFEET insoles are made from a combination of materials, including graphite, creating an insole that has a certain degree of stiffness alongside a certain degree of flexibility. This feature, combined with the shape of the insole, is precisely adapted to the client’s foot, correcting the foot’s posture on one hand, without restricting mobility on the other. This insole also allows for the correction of foot posture characterized by inward or outward collapse (pronation or supination).
Cyclists and spinning participants using SPINFEET insoles will experience a significant improvement in their athletic performance and feeling during and after training. This is due to the reduction of numbness and back and joint pains, easing the rider and allowing them to pedal continuously for longer periods and at higher intensities.
Tennis Insoles
Sport insoles intended for tennis players are required to provide support to the feet when they are subjected to very high pressures. This is because, during a tennis match, players move on a hard surface, at high speed, with short and sudden movements, and with a sharp break in the natural movement flow. For this reason, a tennis player who wants to ensure optimal performance must remember to equip not only with excellent physical fitness and suitable equipment but also with insoles that offer complete protection to their feet and body from damage and injuries.
Functional insoles specially designed to fit tennis players, like those of the Avidor network, change the foot’s posture in the shoe so that the load from the heel area, the heel pad, and the heel itself is reduced. This way, tennis players can avoid wear in these areas, which is expressed in pain and the formation of hard and irritated skin. An important feature of tennis insoles is being hard enough to protect the player from the ground, yet flexible enough to allow full range of movement.
In general, tennis insoles not only contribute to the health of the tennis player but also to their performance in the game. This is done by raising their grip level, improving coordination, and as a result – shortening their reaction time to the opponent’s moves. Today, some of the best Israeli tennis players enjoy the tennis insoles of Avidor: Yoni Erlich, Dudi Sela, Liat Zimmerman, and the list is only growing.
Specialized Sport Insoles for Ball Games
These sport insoles, intended for professional and amateur players participating in ball games held on relatively small courts, such as basketball, volleyball, and handball, are characterized by a large number of jumps, sudden stops, and sharp turns, actions that create continuous load and tension on the feet.
When this load is applied to the feet over long periods, tension increases in the front of the foot. Among other things, this can lead to wear expressed in the hardening of the skin and blisters in certain areas, especially the heel pad. Therefore, the specialized sport insoles for ball games are designed to provide support and cushioning to the foot in general, and to the heel pad area in particular, without creating a sensation of discomfort during the game. They include a slight reinforcement of the insole under the heel edge and special padding for the toe pads that provides longitudinal support to the foot arch.
Specialized Sport Insoles for Soccer
The physical activity characteristic of soccer games involves sharp movements of the body’s power centers, creating a need for the highest level of stability and control over body movements. This need is one of the guiding lines that influenced the design of the specialized sport insoles for soccer by the Avidor network.
The specialized sport insoles for soccer are made from light and flexible materials, allowing for the dispersion of pressures and easing the areas on which most of the force is applied in a soccer game. In addition, soccer insoles have a narrower structure than regular insoles, allowing players using them to insert them into narrow soccer shoes. All these features, in addition to the insole’s shock-absorbing capability and its custom-made production, ensure reduced risk of damage to the feet due to excessive effort during the game.
Specialized Sport Insoles for Aerobic Workouts
The variety of aerobic workouts offered to trainees at different fitness centers is large, but the principle underlying these workouts is one. Whether it’s step aerobics, aerobic dance, aerobox, or another type of aerobic workout, the goal is to improve physical fitness and coordination through a workout involving the whole body.
During such a workout, the body moves in a repetitive cyclic motion that repeats itself over and over. Such movements cause continuous application of load and tension on the entire foot, especially on its rear part. To reduce this load, it is necessary to cushion the foot with a soft and flexible insole, providing support on one hand, yet allowing it to move freely on the other. This is how the specialized aerobic insoles of Avidor were designed.
Avidor’s aerobic insoles allow for mobility, yet are rigid to a certain extent in the toe pad area to provide them support. Additionally, these insoles were designed to provide longitudinal support along the entire foot arch, and are made from a breathable and sweat-absorbing material, like the rest of Avidor’s sport insoles, to ensure maximum comfort during the workout.
Avidor network offers a wide range of orthopedic shoes, some of which are specialized orthopedic shoes for athletes.
