full letter. What do you think?

Dear John Brown
I wanted to comment on the new Reebok shape up shoes and warn all the buyers who are considering them as a work out help. The advertisements say that the Reebok easy tone shoes say that they leave the butt and legs in better shape than regular walking shoes. This is unfortunately not necessarily true. The study that these advertisements are supposable based off of were done by the University of Delaware and only on five women according to the New York well blog. This study showed that 28% increased in gluteus muscles and 11% increase in calf and hamstring muscles. There were no peer reviewed scientific studies and the study was only done on 5 women. In my opinion five women are not enough of a cross section for this kind of advertising. It’s dishonest to advertise things that are not necessarily true. People could buy this product and think that they will help them lose weight and tone their legs and butt this could not happen because only five women were studied and that’s it. Just thought I should for warn those who are thinking that these shoes could solve their weight or non- toned leg problems.
Sincerely,
Trying to help the buyers
