All Interpod control tech orthoses are designed with a plantar fascial groove.

The plantar fascial groove helps to:
  • decrease arch irritation.
  • facilitate the windlass mechanism which acts to stabilise the foot during propulsion.
Windlass mechanism explained:
The plantar fascia attaches to the heel and the base of the proximal phalanx of all toes. When the hallux is dorsifled at the 1st MTPJ joint, it acts as a lever that winds the plantar fascia around the 'drum' of the first metatarsal head (the "windlass effect"). This has the effect of shortening the distance between the hallux and the heel, raising the arch and making the foot a rigid and stable structure during propulsion.
