I ordered a pair if these in June 2012 and wear them, at most, 1x/wk but occasionally go more than a week without wearing them.  On April 20, 2013, the minor snags that appeared fairly quickly in the gusset caused it to fail entirely.  Being that I did not over-wear them, hand washed and dried them, I was disappointed in their overall quality.  I will not purchase this particular brand again.
