This product arrived on time and in excellent condition. These boots have a good arch and seem sturdy. They do look a little cheaper than I anticipated. The tread is great. Size runs true.

I orderd this magazine in August... There should be some type of notation telling customers that it takes up to two months or more befoee the first issue will arrive.......What a waste of time. I could have gone to the library and received this magazine for free to read......I am still wating..... and there is no tracking number, therefore you just don't have a clear date for the arrival of the magazine.......not happy right now,,,,,,

I remember him in the 80's. I found some new tracks of his on youtube. Those tracks grew on me and I bought the CD. It's true, just about every song is great.Slower pace and slightly more acoustic than his 80's work. The songs are more from his heart, which is where every good song comes from.It's that type of album.

Ex Output:
Positive
