MBT Shoes (Read 379 times)

I'm looking to replace my old running shoes, as they are getting to the point where they feel like my feet are on the track, not my shoes.  However, I've just heard of these MBT shoes, and am thinking of doing a switch.  Has anyone ever used these?  They have some for runners, but not sure if they are for serious runners.  The idea is to have a curved sole, instead of flat, so it feels more natural.  Just wondering if someone has insight and knows if these are worth looking into.
