A dynamic orthotic support (1) for the management of plantar fasciitis has a sock (3) with a sole portion (7) formed from a resilient material. The sole portion is shaped such that, when worn, lines of tension are initiated in the sole portion that act to urge a wearers foot into a closed position. At least one resilient reinforcement panel (15, 17, 19, 21) may be attached to the sole portion.
