Choosing shoes for RA

Therapeutic designs are a tough sell

Despite research supporting the use of therapeutic shoes in patients with rheumatoid arthritis, a study from New Zealand suggests that only 5% of patients actually wear prescribed footwear.

The lack of compliance may be related to practitioners’ failure to understand the social and emotional implications of therapeutic footwear for patients—particularly women—with RA, according to a second study from the U.K.
