The toes consist of multiple osseous and soft tissues including tendons, nerves, and ligaments, that support our body weight. Each toe has multiple small bones called phalanges that connect to metatarsals, the longer bones in our midfoot. Each toe is made up of three phalanx bones- the proximal, middle and distal, except for the big toe which only has two phalanges, the proximal and distal. The main function of your toes is to provide posture and balance, support our body weight, and propulsion during the gait cycle. Not only do your toes help thrust your body forward when you walk, they actually help increase the length of your stride allowing you to run faster.
Most common issues occurring in the toes and their joints in athletes
Hammertoes- Hammertoes are contractions of the toe caused by a muscular imbalance in the foot where the tendons on the bottom of the foot over power the tendons on the top of the foot. As the toes contract they may become permanently bent in a flexed position. This deformity often causes pain when wearing closed toe shoes when the bent toe begins to rub against the top of the shoe. The friction can cause a corn to develop.
Corns and calluses- As you age, the fat pad underneath your foot also becomes thinner leading to a condition known as fat pad atrophy. As the skin loses this underlying protective padding, the formation of painful calluses because the skin lies between a bony prominence inside the foot and the shoe or weight bearing surface on the outside. Essentially the skin lies between a rock and a hard place and this can become very painful. Corns are essentially painful calluses that occur on the top or sides of the toe as mentioned above, because of underlying hammertoe deformities that cause the skin on the top or side of the toe to become painful and thickened as the contracted toe rubs up against the shoe or adjacent toe..
Runner's nails- One of the biggest mistakes my patients make prior to any marathon is to not trim their toenails as short as possible. By not doing so, they can experience black toenails that will eventually fall off, cause blistering and bruising. Black toenails are caused by repetitive microtrauma to the nail plate subsequently resulting in small blood vessels bleeding underneath the nail plate forming a bruise known as a subungual hematoma.
Prehab or rehab exercises recommend to care for toe function and mobility
A few exercises I recommend for toe function and mobility are:
Taps can be done from the same position as toe crunches.
You can also stretch your toes with the use of a towel to help elongate the muscles.
Toe rolls are similar to when you tap your fingers from side to side on a table.
The squeeze exercise can be performed from a seated position.
If hammer toe exercises are effective for treating your deformity, other interventions can help. Assess your footwear and avoid any shoes that have a narrow toe box — the front of the shoe where your toes reside. Your shoes should be one-half inch longer than your longest toe. Generally, this is about the size of the tip of your index finger if you have small hands or pinky fingers, if you have large hands. Another technique to determine whether your shoes are appropriately sized, is to trace your foot onto a piece of paper at the end of the day when your feet are most swollen. Then place the shoe over the tracing of the foot. If the tracing of the foot is external to the periphery of the shoe then you know that your shoes are too narrow. I recommend buying your shoes at the end of the day when your feet are most swollen. If your shoes are comfortable at the end of the day when your feet are in their worst shape, then they will feel comfortable through the day. Overall in mild cases of hammertoe deformities, I recommend the use of hammer toe pads, toe spacers, toe socks, custom orthotics, and wider shoe gear can help. In severe cases, surgery is also a viable treatment option.
