The vicious circle being
The vicious circle being buying a pair of traditional running shoes, running in them, experiencing pain and injury, not figuring out why, going back to shoe store to buy another pair of traditional running shoes, running in them, still experiencing pain and injury, still not figuring out why, so going back to the shoe store... Yes, it is quite vicious.
How many of us were there at some point or another? Studies show 67-70% of all runners will experience an injury at least once a year that will sideline them, so I can imagine the majority of us have been there at some point.
I have a friend who keeps playing this same game over and over and over again. I have literally lost count how many pairs of new shoes she has tried, trying to figure out why she is injured all the time and can't run without horrible pain. Yes, MY own friend! It is so true that you can lead a horse to water, but you can't make it drink. Trust me. I've tried. I've even let her borrow my aqua socks, which she ran in and didn't feel any pain, but for some reason, she still is so in love with the looks or persona of the big, bulky, high-heeled running shoes. Go figure! Yes, I feel so sorry for her!
