Amazon is Great!
I purchased these over a month ago and this is not my first pair.  I will continue to buy these as they are the best walking, tone up shoes ever.
Trips to the grocery store are a workout for me as I don't exercise enough.  I can really feel it the next day!
If you buy these shoes, you should know that you need to buy a half size larger than normal unless your feet are really skinny.  I wear a size 6 1/2 and I got a size 7 which works great for me.
