Favorite sneakers giving you trouble?  You’ve bought the same trusty brand, same size for years, but suddenly you have blisters?  Try taking it up a half size!  Yes, the same gruesome gravity that’s grabbed your chin, chest, and upper arms (or should I say wingspans?) may have gotten to your arches.  You’ll go up at least half a size in your 40’s and 50’s and may go higher as the foot widens and flattens, proving once again that aging ain’t no duck walk (or maybe it is).  I recently went up part of a half size, so I wear the bigger size with two pairs of socks.  Perfect!
