Podlink's research and development team trialed in excess of 50 material variations to obtain the optimum comfort, performance and durabilty to form its final design.

Much research is being done around the world to work out what orthosis actually do for people. Their is much anecdotal evidence to suggest orthosis can help many foot conditions. An article published in The Journal of American Podiatric Medicine May 1999 suggested that 'orthotic management is helpful in the treatment of most orthopedic conditions invloving the rearfoot, including plantar fasciitis, Achilles tendonitis, posterior tibial tendon dysfunction, flat foot' Sobel E, Levity S T,Caselli MA Division of Orthopedic Sciences, New York College of Podiatric Medicine

 An article published in  Vol 94 Number 6 542-549 2004 Journal of American Podiatric Medicine concluded that ' it seems that foot orthoses do have a role in the management of plantar fasciitis and that prefabricated orthoses are a worthwhile initial management' the article goes on to say 'at this time, however it is not possible to recommend either prefabricated or customised as being better, and it cannot be inferred that customized orthosis are more effective over time and therefore have a cost advantage.' Karl Landorf, Anne-Maree Keenan, Robert D.Herbert

Orthosis do not weaken arch muscles. A research paper stated 'The study has shown that there was no decrease in muscle strength after the use of foot orthoses for 4 weeks giving no reason to be concerned with unsupported statements that foot orthoses can weaken muscles.' Craig Payne & Gerard Zammit, Dept of Podiatry, School of Human Biosciences, La Trobe University Melbourne, Australia.

 A study said 12% of Podiatrists in Australia and New Zealand are commonly using prefabricated orthoses as their first choice of treatment.
