FAQ - Frequently Asked Questions

LOW ARCH: fallen arch, flat foot

The arch is incapable of cushioning, thus reducing the spring in the wearer’s step or running motion. Displacement of the bones involved

(e.g., buckling of the ankle bone, heel bone) can cause strain on tendons and ligaments. This leads to static imbalance. The BD LOW Arch footbed helps to prevent overpronation

 

MID ARCH: normal foot

The layout of the bones, tendons and ligaments reflects the theoretical norm. The pressure below the foot is distributed over the 3 main support points: heel (20 %), big toe base joint (17 %), small toe base joint (13 %). A BD MID Arch footbed offers optimum pressure distribution for this type of foot, while stabilizing and cushioning at the same time.

 

HIGH ARCH: hollow foot

The long-arch is too high, thus reducing the contact surface. High medial and lateral arches are typically caused by shortening of the  endon structure or high muscle tension. These changes of the foot shape cause friction and pressure points when wearing shoes. A stressed tendon structure is often found throughout the body in this case. A BD HIGH Arch footbed ensures comfortable, even pressure distribution for this foot type.

BD insoles

  • take individual foot types into account
  • help to reduce pressure peaks and distribute pressure evenly
  • absorb impact
  • guide and support the foot during exercise
  • have a stabilizing effect and reduce the risk of injury, thereby protecting the ligaments, tendons and muscles
  • enhance general body posture

The special technology in BD Power Fit Socks enables them to provide evenly distriubuted pressure around the ankle with graduated compression from the bottom to the top. BD powerfit socks gently support muscles and tendons during all levels of sports. This helps keep your legs and feer feeling refreshed after even a long day of skiing, running hiking, ect. The BD power Fit design provides stabilizing support for the whole foot.

BD compression socks

  • help circulation and promote faster regeneration
  • stabilize the tendons and ligaments
  • reduce the risk of injury
  • ensure higher energy levels and stamina
  • provides stabilizing support for the foot

BD offers various methods for analyzing foot type: 3D scan, 2D scan, podoscope and Feet View.

There are also easier methods for determining the type of foot you have, however. Simply place a wet foot on a dry sheet of paper and compare the print with the templates below.

This will quickly show whether you have a normal foot, a fallen arch or a hollow foot. BD categorizes these three foot types as LOW, MID and HIGH arch. The correct print of the foot will allow you to choose a suitable insoles that will support your feet in a more effeicint and stable position, especially for sport and exercise. Even where the foot position appears normal, however, insoles can guide and support the foot and ensure maximum comfort by optimizing the distribution of pressure.

Contrary to the popular belief that sports insoles are only good for running, they have proven they are equally effective in all sporting activity.

In the case of running, the emphasis is on the core properties of cushioning and stabilization. In other sports, insoles are useful for different reasons. Golfers, for example, swear by sports insoles, because they help to prevent fatigue in the leg muscles. In skiing, sports insoles are particularly effective at preventing sore feet (soles) and numbness. Supporting the foot additionally improves the fit of ski boots.

Footballers also favor sports insoles, which distribute pressure points through studs over the entire sole surface, considerably relieving strain on the feet. At the same time, the insoles perform an important support function and reduce the risk of injury from sudden movements and weight shifts.

Sports insoles that fit properly are recommended for both amateurs and professionals, as they take account of individual foot shape, regardless of performance level. Insoles protect and look after the joints and ligaments, enabling wearers to practice sport for longer periods while benefiting from greater stamina and a lower injury risk.

Insoles specially molded for you will support your feet in the correct, neutral position. This is extremely important for people who overpronate or underpronate. The insoles will alleviate periodically recurring pain in the feet, ankle joints and knees linked to plantar fasciitis, Morton’s neuroma, iliotibial band syndrome and other complaints. Studies have shown that effective cushioning can prevent overpronation and underpronation while alleviating pain caused by strain or injury to the foot, ankle or knee.

However, customized insoles will still benefit those who have no acute foot problems and or neutral-type feet! Custom-molded insoles will enable you to enjoy a perfect fit and lasting comfort with all types of shoes. If you spend much of the day on your feet, individualized support through cushioning can ensure your feet and back tire less quickly. Effective support for the feet has a positive effect on the body’s overall kinetic chain. It encourages the feet, legs and also the spine to adopt the correct position.

If you are still not convinced or would like to know more about your foot type, we recommend a foot or movement analysis. These are offered by various sport stores and numerous physiotherapists, trainers, coaches and doctors.

Overpronation is by far the most common type of incorrect foot position. Normal pronation – the body’s way of absorbing impact – lies in the range of 0-6°. In the case of overpronation, the calcaneus (heel bone) rolls inward beyond the aforementioned range and the longitudinal arch is lowered, particularly when the person is making a dynamic movement, but also when they are in a standing position. As a result, the foot turns too far in the medial direction, i.e. inwards, when the person is walking. One indicator of overpronation is excessive wear on the inner side of the person's shoe sole.

This inward movement of the heel results in rotation of the shin bone and thigh bone, which in turn causes the hips to rotate. The consequence is a forward tilt of the pelvis, which generally produces a compensatory movement of the spine: The person's general posture changes, leading to problems with the muscular system and the skeleton.

The most common negative effects of overpronation include the inflammation, overstrain or stress of plantar fasciitis, midfoot pain, Achilles tendon problems, pain in the knees owing to uneven strain and wear, and inflammation in the hips.

Provided the insoles are properly made and used, no. BOOTDOC insoles cause no harm if they are tailored to your foot arch in a neutral position. At first, they may feel strange to wear as the body and rarely-used muscles adjust to a new position.

You should wear the insoles, provided they feel comfortable. If discomfort occurs, however, remove the insoles. It can take days or even weeks to get used to a new insole. Since insoles influence general body posture, changes that manifest themselves in various ways may be noticed from head to toe. Be aware that an established pattern of pressure and movement is slow to change and be "reprogrammed".

A six-month guarantee from date of purchase is provided in accordance with the Austrian Consumer Protection Act.

Most insoles can be thermally adapted. Only some flat versions used in ski rental are unsuitable for this. Your BD retailer will be able to advise you accordingly.

Take care when putting them on: To ensure your Power Fit Socks can be used for a long time, be careful when putting them on. The main cause of damage to the fabric of Power Fit Socks is snagging on rings, fingernails or toenails.

A) Insert your hand into the sock and grasp the foot section by the protuberance of the heel.

B) Pull the material inside out as far as the heel section. Do not unroll the sock while doing this.

C) Pull on the foot section of the sock as far as the heel.

D) Work up the leg inch by inch, grasping the end of the sock and shifting the material upwards in back-and-forth movements. Never pull up the sock by the edge of the material, as this can gradually cause the sock to stretch, slip or wrinkle.

Once you have put on the garment, gently smooth your hands up the material from bottom to top. This will ensure the sock fits snugly around the leg. Once again, do not pull on the edge of the sock!
