I wear 11.5 in trainers so I bought 11.5 in HD (I usually have to wear 12 in all my other steel toe boots/boots) and they fit great. Colleagues at my factory loved them and said they couldn't believe they were steel toes and that they would all get them too! Not heavy at all, they look great, but I'm going to turn them over because I don't want them to rub too hard (I'll use a good quality suede protector later). If you like the blue collar/skater look at work (regular Fridays?) then rock 'em! They definitely fit here in California.
