I found the Tone-Ups to be comfortable, but seem to fit a bit snug.  I have only had them 3 weeks, show this is a preliminary review.

These are quite comfortable, and look decent.  The fit on me runs a bit snug, but acceptable.  Seems to to be very comfortable, and so far do not overheat the foot.

Will be starting a walking program, and plan on using these.

In further consideration, I want to increase the comfort level up a notch.  I find little pressure on the top of the foot (have calcium deposits from years of cleats being overly tight, So foot comfort is judged in 2 areas by me 1) Foot bed support and isolation from impact from the ground 2) Little or no pain or discomfort on the afore mentioned calcium deposits on the top of my feet.  So far, these are good on both accounts.
