I HAVE WORKED IN PRISONS FOR 10 YEARS I BUY THESE BOOTS EVER 8 MONTHS I LOVE THEM YOU DONT HAVE TO BRAKE THEM IN. THE FIRST DAY IS THE BEST DAY THERE SUPER LIGHT YOU CAN RUN ON WET CONCRETE WITH OUT SLIPPING. THERE WATER PROOF YOUR FEET DO NOT SWEAT I LOVE THE ZIPPER ITS REAL HEAVY DUTY. I HAVE NEVER HAD ONE BRAKE I HAVE OWNED 7 PAIRS OF THESE ALPHA FORCE THE ONLY THING THEY WONT MAKE IT THREW A MEATL DETECTOR BUT I WILL BUY THESE AS LONG AS THEY MAKE THEM ROCKY IS KNOWN FOR SLIP PROOF SOLES AND THEY DONT KILL YOUR FEET TO BRAKE THEM IN THESE ARE BY FAR BETTER THEN THORGOOD, MAGUM, SECURITY,WORX, ETC. I HAVE TRYED ALOT OF BOOTS OVER THE YEARS I HAVE VERY SOFT FEET DUE TO MY FOOT BEING BROKEN A WHILE BACK SO SPEND THE MONEY AND BUY GOOD BOOTS YOU GET WHAT YOU PAY FOR IF YOU PRICE THESE IN A STORE THERE 140 BUCKS ALL DAY LONG THIS IS A GREAT DEAL!
