THIS BOOT DID NOT COME IN A 15 SO I GOT THE 14 AND SHOULD HAVE GOT THE 15 IN ANOTHER STYLE BECAUSE I HAVE A 4E WIDE FOOT AND THEY ARE SNUG. I AM OUT IN THE COLD IN WESTERN PA. A LOT OF THE TIME AND SO I PURCHASED A PAIR OF RADIANTEX  FELT INSOLES FOR UNDER THE BOOT LINER ONCE I BROKE THE BOOTS IN. AFTER MORE BREAK IN TIME I WAS ABLE TO ADD MY SUPPORT INSOLES. SINCE I AM ABLE TO WEAR JUST ONE PAIR OF SOCKS I PURCHASED CARHART ARTIC WOOL SOCKS ALSO AND AM NOW ABLE TO SPEND THE DAY OUT SIDE IN - 10 F TEMPS IN WESTERN PA. I CAN JUST STEP INTO THESE BOOTS TO PUT ON AND THE OUTER SHELL KEEP MY FEET DRY ALL DAY. I ROLL THE TOP LINER DOWN AND COVER THE BOOT LINER WITH MY PANTS ROLL THE LINER BACK UP AND TIGHTEN THE TOP WHICH IS VERY EASY TO ADJUST . I MOSTLY LEAVE THE BOTTOM CINCH IN THE SAME PLACE.THE  B0TT0M OF THE BOOTS PROVIDE GREAT TRACTION IN THE SNOW AND SLIPPERY CONDITIONS.
