If it's any help I got Laponos in a 41 which is the same size for all my CL's so far ( the ones I have at 41.5 I have to pad out ). The toe box was ridiculously tight but the length was perfect. Once I stretched them using socks and a couple of painful wears they were just fine. I have long toes which is my problem, if you don't I think you'll find it easier
Do you have a CL outlet near you ? perhaps try on a 36 bootie and see just how tight it is ?
