Had a job interview the other day that required me to wear my dress shoes, something I generally avoid like the plague. Anyway, I hadn't worn these spiffy-looking black slip-ons in probably more than two years, but they still looked good when I pulled them down out of the closet. I didn't put them on until I reached the parking lot of the place I was interviewing at. And I didn't notice that the heels of BOTH shoes had apparently exploded or imploded almost as soon as they hit the cement. BUT, when I crossed one leg over the other during the interview I saw this black "foam" stuff on my pant leg and quickly placed that leg down and my foot on the floor. Everywhere I walked left a trail of this shredded black foam. Fortunately they did not appear to notice and I made it through the interview without that happening - and I got the job as well. Anyway...I now present to you..."Shredding Shoe Soles"...
