Ever since I bought a pair of MBT shoes I have been waiting for the media to jump all over them.

I have been waiting for five months, and finally, there is one little tidbit in People magazine: In Grey's Anatomy "Ellen Pompeo and Katherine Heigl have been wearing sneakers by MBT — whose unusual sole makes wearers mimic the way one walks barefoot on sand, working leg, butt and ab muscles."

Not surprisingly, People magazine misses the best part of the shoes: They make you stand up taller. In fact, the shoes make it physically impossible to slouch. I wear the shoes about two hours a day and they have actually trained me to stand and walk differently — more upright, better posture. (This is probably why Pilates teachers love the shoes.)

You're probably wondering how I am going to relate this to careers. Hold on.

When I was playing professional beach volleyball, one thing I noticed is that all the players had amazing posture. I used to think it was from using our abdominal muscles every time we hit the ball. But when I switched careers and started slouching I did a lot of sit-ups to no avail. Now, after wearing MBT shoes, I realize the great volleyball posture comes from walking in the sand all day.

Here's why you need the shoes for your career: Because people who stand up straight look stronger and more confident, and those are traits people want in leaders. The shoes can actually improve your charisma.
