In Reply: In response to Dr Weintraub, plantar fasciitis is a clinical diagnosis, not a laboratory diagnosis. Magnetic resonance imaging, radiographs, and nerve conduction studies have not been validated in the literature as being diagnostic for plantar fasciitis and they are not used routinely as such in clinical practice.

In contrast with Weintraub's claims, our study did not limit "magnetic application" to only 4 hours per day, 4 days per week. Rather, the protocol suggested this as minimum use. Daily diary responses indicated that the participants typically used the insoles 6 to 7 days per week for 9 to 10 hours per day.
