Have had these shoes, which have been the most comfortable shoes that I have worked in in a long while, for about a year and a half. The tread on the bottom looks like they could be good for a couple of more years yet the soles on both shoes, the right worse, cracked width ways directly to the inside. Curious if this a problem you are aware of plus I have not been able to locate these shoes anywhere. These were purchased at a local Wal-Mart.
