LIKE MOST OF YOU I HAVE WORKED AT MANY DIFFERANT JOBS. I HAVE LEARNED THAT NOT ALL BOOTS ARE MADE FOR THE WORK YOU DO. OUR ENGINEERS ARE THE WORKERS THATS WHO WE LISTEN TO AND MAKE WHAT YOU TELL US YOU WANT. THAT IS WHY THEY SELL AND WHY THEY LAST SO LONG. I WORKED IN LOW COAL SEAM IN THE 70'S. I LEARNED THERE YOU LISTEN TO THE OLDER COAL MINERS TO MAKE IT. THAT IS STILL TRUE TODAY. THESE BOOTS YOU DESIGNED. ANY COMMENTS E-MAIL ME tell me what you want kermit1942@yahoo.com
