How long has it been since you had to buy shoe strings? I remember when you would have to replace them long before you needed new shoes, now when my shoes wear out I can use the strings for something else. Is it the shoes wear out faster or are the strings better than they used to be? Used to have shoes resoled too , now the uppers come apart and the soles are still almost like new. I had a pair of boots years ago I had the soles replaced 2 or 3 times. Haven't had a pair of work boots last more than a year since the 1970s.
