0mm Drop Shoes

I bought a pair of New Balance Minimus Zero shoes and tried jogging on a treadmill with them. It definitely felt like I was running barefoot, which was a surprisingly foreign feeling. Has anyone else gotten a pair of shoes like this? If so how long did it take you to get to a point you were comfortable jogging in them? Any tips for me?

I'm going to try a 5K walk in them tonight.
