3-draw a marker or simply scratch through the hole where you would need to drill in order to insert the NEW SCREWS and NUTS YOU NEED TO GET. I usually wear a size 6 but I was not sure of the actual sizing so I bought a 7. Just the right warm to cool ratio for around the house in the winter, with occassional walks out to the wood pile for firewood. They arrived and had 8 on the bottom of the shoes. I would says if you are taller than 53 you would need the long option. But one of the reasons I?m giving it 4 stars is because theirs not enough pressure on the ears to were it would block out the ambiance of the real world, which would increase the immersion of the experience. I just received these and they are a little big, my foot lifts up when I walk. And the "transparency mode" on these also wasnt as good. Ive been seeing these for several years and couldnt justify spending the money. The boots are comfortable and standing on concrete for 6 to 8 hours a day in the shop my feet dont hurt.
