Modular, Adjustable, Dynamic:

Designed as modular, adjustable and easy to use. PDE/TP
springs for thermoplastic bracing are a perfect solution for:

    benefit from Dorsiflexion & Plantarflexion assistance.

Available in 5 categories of stiffness and common 250mm length.

Cost Effective, Balanced:

Our new Patent Pending spring material is cost effective and ideally balanced for patients requiring:

  • Optimal initial contact foot position
  • Excellent mediolateral stability

Basic guidelines for choosing spring categories:

Basic guidelines for choosing spring categories:
Because every patient has unique needs there are no specific weight limitations that aid in spring choice. Choose the category based on your patient assessment.


Category number three (3) spring is the most common selection and a great to start your evaluation. From here, up/down spring category is based on what works best for the patient. Our simple four bolt system makes changing the spring quick and easy.
