The clinical need targeted by the shoe spring attachment is primarily associated with chronic foot conditions, particularly plantar fasciitis and heel spurs. Plantar fasciitis is a common musculoskeletal condition characterized by pain in the heel and along the arch of the foot, resulting from the mechanical over-stretching of the plantar fascia ligament. This condition is often chronic, with symptoms that can persist for months or even years if not effectively managed. Individuals suffering from plantar fasciitis typically experience sharp, stabbing pain during the first steps in the morning or after prolonged periods of sitting, which can significantly hinder their mobility and overall quality of life.

The clinical need extends beyond just those with plantar fasciitis to include individuals recovering from foot injuries such as stress fractures. These patients often require additional support to alleviate pressure on the heel and facilitate rehabilitation. The attachment aims to address these needs by providing a mechanism that absorbs shock during walking, thereby reducing impact forces on the heel and promoting comfort. By simulating a toe-walking motion, the device also encourages stretching of the plantar fascia, which can be beneficial in alleviating pain and improving flexibility .

Moreover, this product seeks to meet the needs of a diverse user group, including those with biomechanical abnormalities, such as tight Achilles tendons or obesity-related foot issues. These conditions can exacerbate heel pain and necessitate supportive footwear that accommodates their specific requirements. The shoe spring attachment promises to enhance stability and comfort for users who struggle with chronic foot pain, ultimately improving their ability to stand or walk for extended periods.
