I am looking for some shoes to use for daily walks on asphalt and grass.

What are THE most comfortable walking/light hiking shoe?

I used to have a pair of Nikes that were almost like socks. Super light weight. However, they were unstable and caused fatigue due to this.

Right now I'm using a pair of Tod's Driving Loafers which are very nice and comfortable to wear, but not when walking with them (I guess they're made for driving after all).
