Nice fitting shoe - upper sole is flexible and doesn't require any breaking in.

The rubber on the tips and heel feel like bumpers for your shoe - it's not unpleasant and actually very welcome if you scuff your shoes normally.

Note that the soles have the noticeable rubber pieces on the bottom, and you'll notice them the first few times you walk.  In fact, it feels a bit unstable occasionally, depending on where your foot strike falls.  However, that feeling goes away fairly quickly, and it's a comfortable walk from then on out.
