Is This a Result of Getting Older?

Lately I have been having issues feeling comfortable in shoes or more specifically heels.

Is this a result of getting older?  I cannot wear flats to work no matter how cute they are - I am a little too short to wear flats to the office and I happen to think that they look too casual.  I cannot tell you how many pairs of shoes I have ordered and sent back in the past couple of months.  And this does not include when Catherine and I were in Baltimore and I must have tried 5 to 6 pairs of shoes and not bought any.

I am too old to have my feet be uncomfortable for more than eight hours; but, too young to be wearing orthopedic shoes - what a dilemma.
