Imperial Punk Men's Triblend T-Shirt

My son wears these for work as a bartender. They are sturdy, durable and most important comfortable. He is on his feet anywhere from 9 to 12 hours at a time and has been wearing these for years and years. He was looking for an all black shoe and discovered these many years ago. We are concerned that they will eventually be discontinued so he stockpiles. He claims they are best shoe for him for any price.
