I bought these about seven years ago from a local store that specializes in running.  At that time, I weighed in at approximately 220 pounds and was running about 1-2 miles per day in a pair of sneakers I had bought the year before and used only for jogging.  During that time, I had come to accept the fact that running would always be painful (particularly my shins and knees) until I lost a significant amount of weight.

After taking a look at my running gait, the store person recommended these shoes.

Honestly, they look like Frankenstein's running shoes.  Just clunky, and ugly as sin.  I got over the aesthetics QUICKLY.  If you are overweight, and flatfooted, but dedicated to physical fitness, they are just the best.  Seemingly overnight, all leg pain disappeared.  I have not replaced these in 8 years (which is bad) but I never again had the type of pain that came from previous sneakers.  I will be replacing my previous pair (which has held up remarkably well) with a new pair of these.
