Buy at least 1 to 2 sizes above your usual

These boots,like my previous pair of Mammut boots, seem to use a different sizing system to the rest of Europe.
I am usually a shoe size 43 (UK 9) and have average width feet. I ordered these boots in size 44 2/3rd (UK10) which were too small. I think I'll need 45 1/3rd. Thus it is not easy to buy Mammut boots from an online retailer.
