Low Dye strapping is a widely used taping technique in podiatry to alleviate foot pain, particularly from conditions like plantar fasciitis. This rigid adhesive tape application supports the foot’s longitudinal arch, reduces excessive pronation, and offloads strained structures.
Origins and Technique
Developed by physical therapist Tom Low in the mid-20th century, Low Dye strapping targets the medial longitudinal arch to mimic ligamentous support. Clinicians apply zinc oxide or rigid sports tape in layers: starting with a figure-eight around the forefoot and heel, followed by medial and lateral strips to elevate the arch, and anchors at the metatarsals and tibia.
The process begins with skin preparation using tincture of benzoin for adhesion, then baseline strips from the plantar surface up the sides. A key lowermost strip encircles the heel and midfoot, preventing arch collapse during gait. Additional “shuttle” strips weave medially and laterally for reinforcement, typically lasting 3-7 days before reapplication.

Proper technique minimizes skin irritation while maximizing biomechanical control, making it a staple in clinical settings for podiatrists treating overuse injuries.
Biomechanical Mechanism
Low Dye strapping works by limiting subtalar joint pronation, which flattens the arch and stretches the plantar fascia during weight-bearing. It acts as an external “sling,” redistributing ground reaction forces away from the heel and midfoot.
Research indicates it increases navicular height by 5-10 mm immediately post-application, reducing plantar pressure by up to 40% under the heel. This offloads the plantar fascia, Achilles tendon, and tibialis posterior, addressing pain from repetitive microtrauma.
During dynamic gait, the tape resists calcaneal eversion, promoting a more neutral foot posture. This alters kinetic chain loading, potentially easing proximal symptoms like shin splints or knee pain.
Primary Indications
Primarily indicated for plantar fasciitis, Low Dye strapping relieves heel pain from inflamed fascia insertion at the calcaneus. Patients report rapid symptom reduction, often within 48 hours, due to decreased tensile strain.
It benefits other arch-related pathologies, including posterior tibialis tendon dysfunction, where arch support counters insufficiency. Achilles tendinopathy responds as reduced pronation lessens pull on the gastro-soleal complex.
Athletes with fat pad atrophy or metatarsalgia find utility in forefoot anchoring, while golfers or runners use it prophylactically for medial overload.
