McPoil Tissue Stress Relief


The Vasyli – McPoil Tissue Stress Relief pre-fabricated foot orthotic is the result of the collaboration between Vasyli Medical’s Innovation Director, Chairman and Podiatrist Phillip Vasyli and Prof. Thomas G. McPoil PhD, PT, ATC.

It's design incorporates intrinsic features based on the McPoil - Hunt Theory of Tissue Stress. Essentially, the orthotic incorporates a "dual density" approach using a sifter density overlay material to allow for what Tom calls the "normal" amount of pronation, while preventing over or excess pronation with a higher density orthotic shell.

  • High Medial arch for full contact.
  • 1st ray plantar flexor.
  • Mid density EVA.
  • Heat Mouldable.
  • Deeper heel cup.
  • High friction co-efficient top cloth.
  • Dual density.


The tissue stress relief concept is successful in the treatment of common conditions associated with over-pronation such as;


  • Anterior knee pain.
  • Medial tibial stress syndrome.
  • Posterior tibialis tendinopathy.
  • Chronic plantar heel pain: (plantar fasciitis & fasciosis)
  • General arch pain.
  • Mid-tarsal joint pain.


Sizes: XS, S, M, L and XL
