I bought these in a 6W for my son, who, at 8, is a really big kid cursed with really wide feet. He has joined cub scouts and is starting to hike and camp, etc., so I knew he needed something more serious than sneakers. I spent an hour researching wide-width hiking boots on the web and finally found these. I bought them a 1/2 size bigger than his current sneakers to leave room for thicker socks. When he tried them on he was so happy with them that he asked if he could wear them to school. What a HUGE relief. I can't vouch for their waterproof qualities yet. But I do intend to spray them with a waterproofing spray, just as I always did with my own Timberlands. Thanks, Timberland, for remembering the wide-width kids.
