The Katavi's fit my narrow foot well without rubbing blisters.  I wear them tight in the woods so my foot doesn't slip around the wet inside, and they don't bother me.

They don't tend to smell.  If you wear a lot of foam sole shoes you know that some tend to hold odor.  These do not.

They run true to size.

They have good support.

You get what you pay for.  Try em.
