I bought these as inexpensive replacements for my old gym shoes and, so far, they're great. For under $30, you definitely cannot go wrong with these. They are light, comfortable, and the sizing is correct. I've been wearing them for about a month, and they are holding up well as an all-around gym shoe. They are also fairly nondescript, style wise, which is a bonus.  They perform just as well as my more expensive Adidas did, on and off of the treadmill.  I am an experienced runner, and although I haven't worn them over any long distances yet, I imagine they would hold up just fine. Considering the price, it's fair to assume they may break down more quickly than a more advanced running shoe, but that remains to be seen. All in all, for the price, these are definitely a good deal.
