Hi Sue.
The people at Altberg told me that boots MUST be ordered using UK sizes. Also, if the foot is medium to wide, then a 1/2 size bigger than your normal boot fitting should be ordered. For narrow to medium, just order normal boot size. They also told me that sending a drawn outline of the foot would not help them in selecting the correct fitting for you.
Myself, I was incredibly lucky today, in happening upon a paiir of Alpinestars at my local and excellent h***a dealership that actually fit me. Incredibly lucky, because, an identical pair, of the same size were too tight in the fore foot, just like every pair of quality boots I've tried in the last 6 months. Just as I was giving up hope of ever finding a decent pair of cumfy boots, fate has lent a hand providing an accidental wide fitting pair. If that wasn't enough good fortune, they were on sale, as 3 year old stock at less than half price

.
I hope you're as pleased with your Altbergs Sue.
