I'm more willing to believe it was an actual UFO.
And I don't believe in Alien UFOs.

This is the most convoluted conspiracy theory I've heard since the "9/11 was perpetrated by the US" and "Obama's Birth Certificate" nutjobs

actually, that's not true.
Here's what you do - find a running store in your area, go in and have them do a gait analysis. They'll recommend a style of shoes for you.

The price is unlikely to be much higher than you'd pay in any other store, but it's likely to START higher, so be prepared.

My wife went from some pretty serious knee pain/shin splints to a much more comfortable run, and they actually told me "keep the ones you've got and come see us when they wear out".
