I bought a pair of Reebok Easy Tones, I wore them for my 1 hour a day walk for 4 weeks. The bottom of the shoe wore off into the air pocket of the sole and the shoes were not longer any good. I exchanged them for another pair and the same thing is happening again, these shoes are 4 day away from being 4 weeks old. I love the shoes and feel the difference walking in them but I can not afford $99.00 every 4 weeks for shoes. I am very disappointed and I'm sure this is happening to others. I think Reebok should have to make a better product.
