Went out in my Lunarglide3's the other night, and they are pretty worn now. I've done almost 1,000KM in them since I got them! Nike say the average life span is 600KM, so I've done really well with them. I think I'm going to replace them with another pair, just not going to have them custom made this time, as they are LOT cheaper now (the new Lunarglide 4's are coming out end of the summer).
