First, I’d like to say that the article on adult-acquired flatfoot (AAF) was insightful and thorough (see the cover story “A New Approach To Adult-Acquired Flatfoot,” pg. 32, May issue). It is now my reference on AAF. However, I found that the heel pain article left questions unanswered (see “Conquering Conservative Care For Heel Pain,” pg. 48, May issue). I wonder why James Losito, DPM, offered his comments on Extracorporeal Shockwave Therapy (ESWT) while having very limited knowledge of ESWT. Out of the three methods of generating shockwave, Dr. Losito only describes one.
