That makes perfect sense. Thank you, Dr. Barrett, for taking the time to speak with us today. Dr. Gillroy is interested in all aspects of foot care but has taken a keen interest in trauma and in surgery of the foot and ankle. We were fortunate enough to take a few minutes out of Dr. Gillroy's dayfto ask her about footwear and how it can make a difference in the health of your feet. Doctor, most people don't seem put a lot of thought into their choice of footwear. What kind of long-term effects does this have on the health of your feet and what do you recommend as far as footwear choices are concerned?
