This shoe has a mixture of reviews saying either go 1/2 or 1 size down from your normal shoe size. I reckon that this is just for length - the width of the boot should be fine if the size you choose is in the 'narrow' catagory. I would definitely say go down 1/2 a size at the most, maybe don't even size down.

The leather (on the beeswax at least) is THICK and I do not expect it to stretch. On the other hand, its always possible to buy boot heel inserts if the Clarks in your normal size happen to be a bit long.

My details: I tried to guess my size based on my 41 EU and 42 EU dress shoes. I got a 7.5 (B)M US Clarks. Thats maybe a full size gap. Its almost impossible to get my feet in, and they get crushed by the narrowness. I am hopeful that walking will change the shoes and give my feet room, but thats just because I ordered internationally and its not an option to return them.

If I had purchased 1/2 a size closer to my normal shoe size I would be really happy with the solid construction of these. Makes me feel very tall.
