Hi, I have a pair of black lange comp 110's from a few years ago. I noticed that the heel and toe areas are worn. They don't appear that worn to the eye alone, but when a ruler is held at the very end of the lugs, they are nowhere near the DIN standard, which doesn't seem right based on appearance. However, these do not appear to have replacement lugs. The only thing I noticed were 4 very tiny holes on both ends of the boots. All the other comp lines have replaceable lugs, so it just doesn't make sense that one line doesn't..I was thinking that the four holes allow replacement, but I'm not sure. Any help will be greatly appreciated! I'll provide pics.
