I was at DSW and saw that they had the Reebok Easy Tones, but at $100 they were still a bit out of my price range right now. Later I was at Payless and saw they had the Champion version of the Easy Tones for only $30.
I've done a few long walks in them (very long in a couple cases), and so far, I have noticed a marked difference in how my legs feel both while walking and later. My knees don't hurt as much after a long walk, but my calves and thighs are sore the day after.
I'm going to hold off on a formal review of them for a while, to see if, once I resume my normal workout schedule, they add anything to my fitness level or not. But so far, I'm really enjoying them.
