Common Problems With Running Shoes

Mechanical Limitations

• Choosing a proper-fitting running shoe can be difficult at best. Dr. Nirenburg of America's Podiatrist, however, claims it may be impossible because the average foot may undergo four different shapes at any point in time. To illustrate, the static shape is that of the foot at rest, while the weight-bearing shape is when the foot's 26 bones shift during standing. Functional shape occurs during walking or running, and thermal shape is the foot's response to temperature and humidity. It is thus difficult to find a shoe that accommodates each of these shapes, particularly as the foot can expand by one-and-a-half shoe sizes during jogging. What may ensue are painful injuries, such as Morton's neuroma. This is a growth on one of the nerves that causes severe pain and burning on the toes or ball of the foot.

Shin Splints

• The term "shin splints" refers to leg pain that occurs between the ankle and knee. This pain, which can affect runners of all ages, is commonly caused by inflammation around the tibia. Running shoes are one of the greatest contributing factors to shin splints, as those that do not provide adequate shock absorption and support can actually cause shin splints to develop.

  Northcoast Footcare suggests that purchasing a supportive shoe is one of the most important steps in preventing shin splints. A flexible shoe, on the other hand, will increase a runner's chances of developing this condition. In addition, some shoes, particularly those for distance running, are specifically designed to prevent such injuries as shin splints. Those shoes absorb the shock of running by sending shock waves up the leg and to the torso, thus providing a more comfortable run.

Blisters

• According to Northcoast Footcare, friction blisters are one of the most common foot injuries sustained by runners. They commonly develop on the back of the heels and on the toes. Considered a defense mechanism of the body, blisters are occasionally unavoidable. In most cases, however, blisters occur because of running shoes. Runners Rescue explains that shoes that are too tight or too loose can cause friction in the toes or sole areas of the foot. The best method of prevention is therefore purchasing running shoes that fit well and are intended for the purpose of running. Feet can also be lubricated with Vaseline or talcum powder to reduce friction inside the shoe.

Tendonitis

• Achilles tendonitis and related calf injuries are those most commonly suffered by runners. Running shoes that fit properly can help prevent injuries to the Achilles tendon and support those who are recovering from such injuries. Conversely, the wrong shoe can also increase a runner's chances of developing tendonitis, prolong recovery and lead to a reoccurrence of injury.

  The right shoe to prevent tendonitis is one with moderate heel height and cushioning.Too little cushioning can cause the Achilles tendon to stretch, while too much can reduce the tendon's length and lead to injury at a later time. Shoes should also have a flexible sole and correct arch support for the wearer. For example, flat feet need more arch support, while high-arched feet need less. Both types of feet are linked to a greater chance of tendonitis, so it is important for runners to know their foot shape and purchase the right shoes for balance.

Plantar Fasciitis

• One problem that often develops with older, worn running shoes is plantar fasciitis, or heel pain. Afflicting one million runners every year, plantar fasciitis is the result of too much stress in the plantar fascia ligament located along the foot's bottom. That stress, usually the result of low-quality or worn shoes, can lead to tearing, inflammation and pain. New running shoes that do not fit properly can also lead to plantar fasciitis. The solution, and best method of prevention, is to therefore purchase high-quality shoes with adequate support and stability, and replace them as needed.
