Overview
A Hammer toes is a deformity of the middle joint of a toe, producing a clenched, clawlike appearance in the affected digit. The tendons in the toe become abnormally contracted, causing the toe to bend downward, which, in turn, forces the joint to protrude upward. A mallet toe is a deformity in which the end joint of a toe becomes bent downward, so that the toe curls underneath itself. In either case the affected joints are stiff, and often the toe cannot be straightened out. Constant rubbing against shoes may furthermore cause a painful corn (a round patch of rough, thickened, calloused skin) to develop over the joint or at the tip of the affected toe. Hammer and mallet toes may occur in any toe, although the second toe is the most common site. These deformities are often painful and limit the toe?s range of motion-sometimes requiring surgery.
Causes
The muscles of each toe work in pairs. When the toe muscles get out of balance, a hammer toe can form. Muscle imbalance puts a lot of pressure on the toe's tendons and joints. This pressure forces the toe into a hammerhead shape. How do the toe muscles get out of balance? There are three main reasons. Your genes, you may have inherited a tendency to develop hammer toes because your foot is slightly unstable - such as a flat foot. But high-arched feet can also get hammer toes. Arthritis. Injury to the toe: ill-fitting shoes are the main culprits of this cause. If shoes are too tight, too short, or too pointy, they push the toes out of balance. Pointy, high-heeled shoes put particularly severe pressure on the toes.
Symptoms

Overview
The Achilles tendon is the largest tendon in the body; connecting the calf muscles to the heel. An Achilles tendon rupture prevents the tendon from performing its function of pulling the foot and ankle downward during walking, running and jumping. Most ruptures occur about four to six inches above the heel, but the tendon can also tear where it meets the heel bone.
Causes
Common causes of an Achilles tendon rupture include the progression of or the final result of longstanding Achilles tendonitis or an overuse injury. An injury to the ankle or a direct blow to the Achilles tendon. As a result of a fall where an individual lands awkwardly or directly on the ankle. Laceration of the tendon. Weakness of the gastrocnemius or soleus muscles in people with existing Achilles tendonitis places increased stress on the tendon. Steroid use has been linked to tendon weakness. Certain systemic diseases have been associated with tendon weakness. A sudden deceleration or stopping motions that cause an acute traumatic injury of the ankle. Injection of steroids to the involved tendon or the excessive use of steroids has been known to weaken tendons and make them susceptible to rupture. Contraction of the calf muscles while the foot is dorsiflexed (pointed toward the head) and the lower leg is moving forward.
Symptoms

Overview
The majority of people will experience a flattening of the arch of the feet as we age. This is a natural part of the aging process for most, as the years of abuse we put on our feet causes weakening of the soft tissue structures that support the arch of the foot and gravity dictates that the feet tend to flatten out. When flattening of one of the feet occurs rapidly over a relatively short period of time this may signal a more serious problem.
Causes
Overuse of the posterior tibial tendon is often the cause of PTTD. In fact, the symptoms usually occur after activities that involve the tendon, such as running, walking, hiking, or climbing stairs.
