Well, it can't hurt to try a pair, since the men's ones are not wholly silly in appearance. After rent day I think!

However, I believe I am right in saying that plantar fasciitis is often triggered by repeated minor injuries to the foot (eg from a lumpy or misshapen insole).

Mine is only a mild nuisance mostly, but is concentrated at the rear attachment of the plantar fascia, although sometimes there is a slightly "scrunchy" feel in the general area of the front attachment.
