An orthopedic casting slipper kit (21) including a resilient fabric impression slipper (23) formed to extend on a patient's foot (27) from a plantar aspect or surface (29) to about one-third of the way from the base of the toes to the dorsum of the foot. A longitudinally resiliently extensible band (37) is provided on the slipper (23) proximate the open end (33) and an arch strap , (39) dimensioned to span transversely over the dorsum (30) of the foot (27) is used to pull the impression slipper (23) up into contact with the arch (35) of the foot to prevent bridging of the arch. A method of using the arch strap (39) to aid in conformance also is disclosed.

Why it's free to use
- Filed September 28, 2004 and granted July 17, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended September 28, 2024.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 28, 2026.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
