Hi All,

Im a student and just want to clarify something about a patient with PTTD and orthotics.

If their career requires them to be moving/walking around all day then I suspect leather would not be the most appropriate top cover (does not absorb moisture and can be unhygienic if one sweats).
I thought maybe neoprene would be the best as it does absorb moisture, but it's downside is that it can be compressed easily.

Could anyone offer some suggestions on what would be the most appropriate top cover for someone experiencing PTTD?

Thanks!

 

Before Robin P gets in and steals my thunder again, It depends (HA! In your face Robin).

Personnally, I prefer 1mm low density EVA to leather for a topcover in patients who will wear their devices very heavily. Its robust and does not go hard when it is sweated into. However it depends on many other variables. What is the cover covering? Does it have to conform into a heel cup? Is it to be worn in a heavy boot indoors or a light shoe outdoors? What is the intention of the device (the topcover may change the force vector)? Is cushioning required? Whats the climate? What is the foot like? etc etc etc.

It depends. There will never be a single right answer, just a list of factors to consider when reaching it for yourself.

 

You could use the following, cool max, Nora Lunairmed (which is my favourite).
Any low-medium density nora is great, a closed cell material and very well wearing.
Or an alternative to that would be 3mm Algeofoam.

 

To be honest, I was just going to jump right in with 1mm EVA. It's cheap, thermoforming, closed cell and can be wiped down. Resonably high friction to prevent "sliding down the slope"

But really.........it depen...just use 1mm EVA!

That company sells as coolmax rivestimeto for orthotics??
There is also thermolite??
Thanks

 

I have moved the posts so the Op gets the answers they require not more confused

to Will increasing the friction of the topcover increase the supination resistance of the foot? And if so, how and why?

 

Yampi?

Hardwearing
Non-insulating
Non-absorbant
Easy to clean
Is thin so can be applied to many materials as a top cover without compromise

 

I like to use Spenco because it is more cushiony but more importantly I have it extended about 1 1/2" (~4cm) medially into a soft flange that pushes into the medial side of the shoe. It keeps them from pronating off the device and gives the navicular a cushion to hit against. It really helps for my PTTD patients.
