I was looking for lightweight, breathable running shoes.  These Adidas running shoes are attractive and lightweight.  The fabric seems to be a thin, firm net allowing air to pass easily.  I really like the style and design of the shoes.  I heard about these running shoes but was unable to find them in any local stores.  I confidently ordered size six online because I always wear size six gym shoes.  The shoes ran big in both length and width.  I have narrow feet but never had a problem with gym shoes being wide.  Even after tying the shoe laces very tight, the shoes were still loose.  I was later able to try the shoes on in a 5 1/2.  The 5 1/2 was okay in length but still very loose.  I really did like these shoes and was sad to return them.  I probably would have given five stars if the shoes fit properly.
